To decrease the type II error in a hypothesis test while maintaining the type I error at its current level, we need to increase the sample size.

Type I error shows when we reject a null hypothesis which is actually true. Type II error shows when we fail to reject a null hypothesis which is actually false.

Increasing the sample size can decrease the probability of making a Type II error, as it increases the power of the hypothesis test. Probability of correctly rejecting a false null hypothesis is called power.

By increasing the sample size, we can increase the power of the test while maintaining the significance level (and thus the type I error) at its current level.

This means that we will be less likely to miss a true effect (i.e., lower the probability of making a Type II error) while still controlling the probability of false positives (i.e., Type I error) at the desired level.

The critical value zₐ/₂ that corresponds to an 83% level of confidence is approximately 1.381.

To find the critical value zₐ/₂, we need to determine the value that leaves an area of (1 - α)/2 in the tails of the standard normal distribution. In this case, α is the complement of the confidence level, which is 1 - 0.83 = 0.17. Dividing this value by 2 gives us 0.17/2 = 0.085.

To find the z-value that corresponds to an area of 0.085 in the tails of the standard normal distribution, we can use a standard normal distribution table or a statistical calculator. The corresponding z-value is approximately 1.381.

Therefore, the critical value zₐ/₂ that corresponds to an 83% level of confidence is approximately 1.381.

The ending dollar balance in inventory, using the FIFO method, is $973.

The cost of each sold unit must be tracked according to the sequence of the unit's purchase if we are to use the FIFO (First-In, First-Out) approach to calculate the ending dollar balance in inventory.

Let's begin by utilizing the FIFO approach to get COGS or the cost of goods sold. In order to attain the total number of units sold, we first sell the units from the earliest purchase (First Purchase) before moving on to the units from the second purchase (Second Purchase).

First Purchase:

Number of Units: 130

Cost per unit: $3.1

Second Purchase:

Number of Units: 451

Cost per unit: $3.5

We compute the cost based on the cost per unit from the First Purchase until we reach the total amount sold to estimate the cost of goods sold (COGS) for the 303 units sold:

Units sold from First Purchase: 130 units

COGS from First Purchase: 130 units × $3.1 = $403

Units remaining to be sold: 303 - 130 = 173 units

Units sold from Second Purchase: 173 units

COGS from Second Purchase: 173 units × $3.5 = $605.5

Total COGS = COGS from First Purchase + COGS from Second Purchase

Total COGS = $403 + $605.5 = $1,008.5

To calculate the ending dollar balance in inventory, we need to subtract the COGS from the total cost of inventory.

Total cost of inventory = (Quantity of First Purchase × Cost per unit) + (Quantity of Second Purchase × Cost per unit)

Total cost of inventory = (130 units × $3.1) + (451 units × $3.5)

Total cost of inventory = $403 + $1,578.5 = $1,981.5

Ending dollar balance in inventory = Total cost of inventory - COGS

Ending dollar balance in inventory = $1,981.5 - $1,008.5 = $973

Therefore, the ending dollar balance in inventory, using the FIFO method, is $973.

The forecast for May using a five-month moving average is 39 (Option E).

Moving average is used for smoothing out time series data to find any trends or cycles within the data. A five-month moving average is the average of the past five months. To calculate the moving average, add up the sales for the previous five months and divide it by five.

According to the question, the sales for the previous five months are: Nov. 39 Dec. 27 Jan. 40 Feb. 42 Mar. 41 April 47

We have to add the sales of these five months, which gives:

27 + 40 + 42 + 41 + 47 = 197

To find the moving average for May, we divide this sum by 5:

197 / 5 = 39.4

Since we have to round the answer to the nearest whole number, we round 39.4 to 39, which is option E.

Step-by-step explanation:

The number of tiles to cover rectangular room are 102 tiles.

The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.

Given that, a worker is tiling the floor of a rectangular room 12 feet by 15 feet.

Here, the area of a rectangular room =15×12

= 180 square feet

The tiles are square with sides of \(1\frac{1}{3}\) =4/3 feet

Area of a square tile = (4/3)²

= 16/9 square feet

Number of tiles = 180÷16/9

= 180×9/16

= 1620/16

= 101.25

≈ 102 tiles

Therefore, the number of tiles are 102 tiles.

The equation to represent the function is f"(x) = (-1/ x + 3 )+ 8

The asymptotes is (x, y) = (-3, 8)

Given,

Let the reciprocal function be:

f(x) = 1/x

First, it was reflected across the x-axis.

The rule is: (x,-y)

So, we have:

f'(x) = -1/x

Next, translated 3 units left.

The rule is: (x, y) => (x + 3, y)

So:

f"(x) = -1/ x + 3

Lastly, translated 8 units up.

The rule is: (x, y) => (x, y + 8)

So:

f"(x) = -1/ x + 3 + 8

To get the vertical asymptote, we simply equate the denominator to 0.

i.e.

x + 3 = 0

x = -3

To get the horizontal asymptote, we simply equate y to the constant.

The probability that the second traffic light is red, given that the first light is red is approximately 0.729 or 72.9%.

To find the probability that the second light is red, given that the first light is red, we can use the concept of conditional probability. The conditional probability of an event B happening, given that event A has already occurred, is denoted as P(B|A).

In this scenario, event A represents the first traffic light being red, and event B represents the second traffic light being red. We are given that the probability of event A, P(A), is 0.48, and the probability of both events A and B occurring, P(A and B), is 0.35.

The formula to calculate conditional probability is:

P(B|A) = P(A and B) / P(A)

Plugging in the values we have, P(B|A) = 0.35 / 0.48.

Dividing 0.35 by 0.48, we find that the probability of the second traffic light being red, given that the first light is red, is approximately 0.729.

Therefore, the probability that the second light is red, given that the first light is red, is approximately 0.729 or 72.9%.

They have a perimeter of 40 meters, and an area of 168 square meters. Therefore, either set of dimensions would work for Chase's fence.

Let's assume the rectangular plot of land has length L and width W. We can use the given information to set up the following system of equations:

2L + W = 40 (since there are three sides and the total length of fencing is 40 m)

LW = 168 (since the area of the land is 168 square meters)

Solving the first equation for W, we get:

W = 40 - 2L

we get:

L(40 - 2L) = 168

we get a quadratic equation:

\(2L^2\) - 20L + 84 = 0

Using the quadratic formula, we can solve for L:

L = (20 ± sqrt(\(20^2\) - 4(2)(84))) / (2(2))

L = (20 ± 4sqrt(11)) / 4

L = 5 ± sqrt(11)

Therefore, we have:

L = 5 + sqrt(11) or L = 5 - sqrt(11)

W = 30 - 2sqrt(11) or W = 30 + 2sqrt(11)

(5 + sqrt(11)) m by (30 - 2sqrt(11)) m

and

(5 - sqrt(11)) m by (30 + 2sqrt(11)) m

Note that both sets of dimensions satisfy the given conditions: they have a perimeter of 40 m (2L + W = 40) and an area of 168 square meters (LW = 168).

Experimental design involves manipulating variables to observe their effect on an outcome, while correlational design observes the relationship between variables without manipulation.

In an experimental design, the researcher controls the independent variable(s) and randomly assigns participants to different levels of the independent variable(s) to observe the effect on the dependent variable. This allows for conclusions about cause-and-effect relationships between variables.

In contrast, in a correlational design, the researcher measures two or more variables to observe their relationship without manipulating them. Correlational studies can be used to describe the strength and direction of a relationship between variables, but they cannot establish causality.
