If the data is symmetrical, then the mean is the best measure of central tendency to use, and the standard deviation is the best spread to use.

If the data is asymmetrical, the median is the best measure of central tendency to use, and the inter-quarterly range is the best spread to use.

A histogram for symmetrical data will give a symmetrical shape, and the mean, median and mode will all be the same value. Therefore, the best measure of the central tendency to use is the mean. The standard deviation shows how far away the values in a given data set are from the mean, and since the mean is used as the measure of central tendency in this case, the standard deviation should be used as the spread.

A histogram for a an asymmetric data set will give an asymmetric shape, and the mean is not always equal to the median. Therefore, the best measure of central tendency to use is the median. The inter-quarterly range shows the range of the middle 50% of a certain data, which is considered from the median value. Since the median is used as the measure of central tendency in this case, it is wise to use the inter-quarterly range as the measure of spread.

When events are overlapping

formula: P(A or B) = P(A) + P(B) - P(A and B)

=======

P(A or B) = 4/11 + 3/11 - 2/11

P(A or B) = 7/11 - 2/11

P(A or B) = 5/11

Answer:

Step-by-step explanation:

Given:

We can construct a Venn diagram to help answer this question (see attached).

Place 2/11 in the overlapping part.  Then calculate the remaining probabilities:

P(A) - P(A ∩ B) = 4/11 - 2/11 = 2/11

P(B) - P(A ∩ B) = 3/11 - 2/11 = 1/11

P(A' ∩ B') = 1 - 5/11 = 6/11

The critical t-value is approximately 1.753.

To find the critical value for a 96% confidence interval with a sample size of 15, we need to determine the t-value from the t-distribution table. The t-distribution table is a statistical tool used to determine the probability of a t-value given the degrees of freedom (df) and the desired level of significance (α).

In this case, we have a sample size of 15, which means our degrees of freedom are 14 (n - 1). Looking at a t-distribution table for 14 degrees of freedom and a 96% confidence interval.

This means that if we were to construct a confidence interval from a sample size of 15, the margin of error would be calculated by multiplying the critical t-value of 1.753 by the standard deviation of the sample and dividing by the square root of the sample size. The resulting interval would contain the population mean with 96% confidence.

It's essential to note that the critical value will change as the sample size and confidence level change. Therefore, it's crucial to use the correct table to find the corresponding critical values for a given dataset's sample size and confidence level.

The mean of the sampling distribution of p-hat is  p = 62.44%.

The sampling distribution of p-hat can be defined as the distribution of sample proportions. If we calculate sample proportions from multiple random samples of the same size from the same population and construct a frequency distribution of these proportions, we obtain a sampling distribution of p-hat.

The sample proportion (p-hat) is defined as the number of individuals in a random sample that possesses the characteristic of interest divided by the size of the sample. For a large number of samples, the frequency distribution of the sample proportions is a normal distribution, called the sampling distribution of p-hat.

The mean of the sampling distribution of p-hat is given by the formula μp-hat = p, where p is the population proportion. In this case, the population proportion is 62.44% (given in the question).

Therefore, the mean of the sampling distribution of p-hat is

The probability that fewer than 3 of them use their smartphones in meetings or classes is 0.0366.

The binomial probability distribution is a discrete probability law with two parameters: trial number (n) and success probability (p) (p). When there are two mutually exclusive outcomes of finite trials, the binomial distribution is utilised.

The probability that a specific 3 people all use their smartphones in meetings or class is 0.53³.

Probability that remaining 7 people do not use their phone is 0.47⁷

¹⁰C₃ = 10*9*8/(3*2*1) = 120.

Thus, the probability of exactly 3 people using their smartphones in meetings or in class is 10C3*0.533*0.477, or 0.0905.

So, adding up the 3 possibilities (that 0 of them, 1 of them, or 2 of them use their smartphones in meetings or class) we get

none of the provided options (a, b, c, d) appear to be accurate or close to the minimum space required.

To determine the minimum space required for a male restroom design with the given plumbing requirements, we need to consider the minimum space required for water closets and lavatories.

The minimum space required for water closets is typically around 30-36 inches per unit, and for lavatories, it is around 24-30 inches per unit.

Since the design requires a minimum of 12 water closets and 13 lavatories, we can estimate the minimum space required as follows:

Minimum space required for water closets = 12 water closets * 30 inches = 360 inches

Minimum space required for lavatories = 13 lavatories * 24 inches = 312 inches

Adding these two values together, we get a total minimum space requirement of 672 inches.

Using the difference of square formula,

\(x^2 - y^2 = (x+y)(x-y)\\with,\\x = 4a^2,\\y = 2a+1,\\we \ get,\\(4a^2+2a+1)(4a^2-2a-1)\)

The number of square units enclosed by the polygon is 18.

First, count the number of dots that are enclosed by the polygon (including those on the boundary). There are 14 such dots.Next, count the number of dots on the boundary of the polygon. There are 8 dots on the boundary.Each of the dots on the boundary corresponds to a line segment of the polygon.

So, the perimeter of the polygon is 8 units (the length of each of these line segments).Now, we can use Pick's theorem to find the area of the polygon. Pick's theorem states that A = i + b/2 - 1, where A is the area of the polygon, i is the number of dots inside the polygon, and b is the number of dots on the boundary of the polygon.

So, plugging in the values we have: A = 14 + (8/2) - 1 = 14 + 4 - 1 = 17

Therefore, the area of the polygon is 17 square units.However, we have to remember that the dots are spaced one unit apart, horizontally and vertically.

Therefore, each square that is enclosed by the polygon has an area of 1 square unit. We counted 17 such squares, so the total area enclosed by the polygon is 17 square units.

The required anti-derivative of \($-\frac{1}{2x}$\) \(is -\frac{1}{2} \ln|2x| + C$\).

An integral is the continuous equivalent of a sum in mathematics, and sums are used to compute areas, volumes, and their expansions. One of the two basic processes in calculus, along with differentiation, is integration, which is the process of computing an integral.

the integral of \(-\frac{1}{2x}$\) can be written in as:

\($$\int -\frac{1}{2x} ,dx$$\)

To solve this integral, we can use the substitution method. Let u=2x, then \(du/dx=2$\) or \(dx=du/2$\). Substituting these into the integral, we get:

where C is the constant of integration. Substituting back u=2x, we have:

\($$\int -\frac{1}{2x} ,dx = -\frac{1}{2} \ln|2x| + C$$\)

a. The 96% cοnfidence interval fοr the difference in prοpοrtiοns is (0.004, 0.076).

b. The difference in prοpοrtiοns is significantly different frοm 0 at the 96% cοnfidence level.

The cοre οf the science οf statistics is the research and develοpment οf methοds fοr cοllecting, analyzing, and presenting empirical data.

(a) Tο estimate the difference in prοpοrtiοns οf parts prοduced within specificatiοns by the twο shifts, we can use the fοrmula fοr the cοnfidence interval fοr the difference between twο prοpοrtiοns:p1 - p2 ± z*√((p1(1-p1)/n1) + (p2(1-p2)/n2))

where p1 and p2 are the prοpοrtiοns οf parts prοduced within specificatiοns fοr the day and night shifts, respectively, n1 and n2 are the sample sizes, and z is the z-scοre cοrrespοnding tο the desired cοnfidence level.

Using the given sample prοpοrtiοns and sample sizes, we have:

p1 = 188/200 = 0.94

p2 = 180/200 = 0.90

n1 = n2 = 200

z = 1.75 (cοrrespοnding tο a 96% cοnfidence level)

Plugging these values intο the fοrmula, we get:

0.94 - 0.90 ± 1.75*√((0.94(1-0.94)/200) + (0.90(1-0.90)/200))

= 0.04 ± 0.042

Sο the 96% cοnfidence interval fοr the difference in prοpοrtiοns is (0.004, 0.076).

(b) Tο determine if the difference in prοpοrtiοns is significantly different frοm 0, we need tο check if the cοnfidence interval includes 0. Since the cοnfidence interval dοes nοt include 0, we can say that the difference in prοpοrtiοns is significantly different frοm 0 at the 96% cοnfidence level.

(c) The hypοtheses οf interest are:

H0: p1 - p2 = 0 (there is nο difference in the prοpοrtiοns οf parts prοduced within specificatiοns by the twο shifts)

Ha: p1 - p2 ≠ 0 (there is a difference in the prοpοrtiοns οf parts prοduced within specificatiοns by the twο shifts)

Tο perfοrm the significance test, we can use the z-test fοr the difference between twο prοpοrtiοns. The test statistic is

z = (p1 - p2) / √((p1(1-p1)/n1) + (p2(1-p2)/n2))

Using the same values as befοre, we get:

z = (0.94 - 0.90) / √((0.94(1-0.94)/200) + (0.90(1-0.90)/200))

= 2.02

The p-value fοr a twο-sided test at a significance level οf 0.04 is apprοximately 0.044. Since the p-value is less than the significance level, we can reject the null hypοthesis and cοnclude that there is a statistically significant difference in the prοpοrtiοns οf parts prοduced within specificatiοns by the twο shifts.

According to Pythagorean theorem, the length of BE is 2√(61) units.

To solve this problem, we need to use the Pythagorean Theorem, which tells us that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, we can see that triangle ABE is a right triangle, with AB as the hypotenuse and BE and AE as the other two sides. Therefore, we can use the Pythagorean Theorem to find the length of BE.

To do this, we first need to find the length of AE. Since triangle ADE is a right triangle with a hypotenuse of length 4 and one leg of length 2, we can use the Pythagorean Theorem to find the length of the other leg, which is AE. Specifically, we have:

AE² + 2² = 4² AE² + 4 = 16 AE² = 12 AE = √(12) = 2√(3)

Now we can use the Pythagorean Theorem again to find the length of BE. Specifically, we have:

BE² + (2√(3))² = AB² BE² + 12 = (2AB)²

[since AB = AC = CD = DE = 4]

BE² + 12 = 16² BE² + 12 = 256 BE² = 244 BE = √(244) = 2√(61)

Math SAT scores explain about 98.7% of the variation in the total SAT scores.

In statistics, correlation or dependence exists as any statistical relationship, whether causal or not, between two random variables or bivariate data.

A correlation exists as a statistical measure (expressed as a number) that defines the size and direction of a relationship between two or more variables. A correlation between variables, however, does not automatically mean that the change in one variable exists as the cause of the change in the values of the other variable.

Since r² exists = (0.9935)² = 0.9870, we interpret r² as 98.7% of the variation in the y variable exists explained by the x variable.
