The p-value (0.0001) is less than α = 0.05. Based on this, we should reject the null hypothesis.
What is a null hypothesis?A null hypothesis (H₀) can be defined the opposite of an alternate hypothesis (H₁) and it asserts that two (2) possibilities are the same.
How to calculate value of the test statistic?The test statistic can be calculated by using this formula:
\(t=\frac{x\;-\;u}{\frac{\delta}{\sqrt{n} } }\)
Where:
x is the sample mean.u is the mean.is the standard deviation.n is the number of hours.For this clinical trial (study), we should use a t-test and the null and alternative hypotheses would be given by:
H₀: p = 0.028
H₁: p > 0.028
For the sample proportion, we have:
Sample proportion, P = 28/888
Sample proportion, P = 0.032.
Next, we would calculate the t-test as follows:
\(t=\frac{0.032\;-\;0.028}{\frac{0.02 \times 0.028}{888 } }\\\\t=\frac{0.004}{\sqrt{\frac{0.00056}{888 } }}\)
t = 0.004/0.00079
t-test, t = 5.06.
For the p-value, we have:
P-value = P(t > 5.06)
P-value = 1 - P(t < 5.06)
P-value = 1 - 0.9999
P-value = 0.0001.
Therefore, the p-value (0.0001) is less than α = 0.05. Based on this, we should reject the null hypothesis.

w(t)=5.5 t+79.5 is the equation for the relationship between weight and the number of months.
What is meant by Function?A mathematical function from a set X to a set Y assigns exactly the same number of elements from Y to each element of X.
The sets X and Y collectively constitute the domain and codomain of the function.
a mathematical expression, rule, or law that establishes the relationship between two variables, one of which is independent, and the other of which is dependent.
Mathematics is filled with functions, which are crucial for creating physical connections in the sciences.
If, y = MX + b
Then m, the slope, is 5.5.
We need to find b.
When x=11, y=140, so: (140)=(5.5)(11)+b.
140=60.5+b
b=79.5
The values for x, y, and m are plugged in.
After simplifying, we take 60.5 off both sides.
This makes the equation:
y=5.5 x+79.5

Suppose the heights of 18-year-old men are approximately normally distributed, with mean 66 inches and standard deviation 5 inches. What is the probability that an 18-year-old man selected at random is between 65 and 67 inches tall?
Answers
Answer: We can start by standardizing the values using the standard normal distribution:
z_1 = (65 - 66) / 5 = -0.2
z_2 = (67 - 66) / 5 = 0.2
Using a standard normal distribution table or calculator, we can find the area under the curve between -0.2 and 0.2:
P(-0.2 < Z < 0.2) = 0.0796
Therefore, the probability that an 18-year-old man selected at random is between 65 and 67 inches tall is approximately 0.0796 or 7.96%.

like some people don't get the meaning of true beauty
I believe that people should look at the beauty of diversity and understand that flaws and imperfections are what make the human race beautiful. People shouldn’t compare themselves to celebrities or models because it is difficult to look exactly like that person, we are all created individually and uniquely, thus we aren’t meant to look exactly like one another. Rather than constantly comparing ourselves to one another, we should realize that we are all beautiful in our own way. I believe that if people live with this mentality they will be happier and comfortable with themselves.
I believe that true beauty comes from within. Outer looks and physical beauty eventually disintegrate, but inner beauty will always remain. The personality and heart of every individual are so unique and special to that person, thus making them truly beautiful. I believe that people that possess this true type of beauty radiate and bring a special light onto others everyday. Inner beauty lights up a person’s face and brings warmth to others. This type of beauty is so unique to individuals and will always remain, unlike outer beauty. As opposed to outer beauty, inner beauty is what makes a person who they are; it makes them unique and special in many ways. The beauty within a person transcends outwardly, thus making a person even more beautiful than they actually appear to be. According to Elizabeth Kubler- Ross “People are like stained-glass windows. They sparkle and shine when the sun is out, but when the darkness sets in their true beauty are revealed only if there is a light from within”.
I believe that if people live with this mentality that everyone is beautiful inside and out, the world will be a happier place and everyone will be accepted despite their differences.

If we were to break up the scatterplot into 4 quadrants; what would data points in the top left, bottom left, top right and bottom right say about the relationship concerning time spent on phone and battery life? For this example, in which quadrant(s) do the data points lie.)
Answers
The scatterplot will show that there is a negative relationship between time spent on the phone and battery life remaining.
How to explain the scatterplotThe scatterplot shows a clear negative relationship between time spent on the phone and battery life remaining. As time spent on the phone increases, battery life remaining decreases. The regression line also shows a negative slope, which confirms this relationship.
In bottom right, data points in this quadrant represent times when the battery life was low and the time spent on the phone was high. This is the most likely quadrant for data points to fall in, as it represents times when the phone was being used heavily.
In this example, all of the data points fall in the bottom right quadrant, which confirms that there is a negative relationship between time spent on the phone and battery life remaining.

what is the vertex of x^2 + 4x - 12
Answers
Answer:
\((-2, -16)\\\)
Explanation:
The vertex of a quadratic function which gets plotted as a parabola is either the minimum or maximum (x, y) value of that function.
The following rule applies to finding the x value of the vertex
\(\mathrm{The\:vertex\:of\:an\:up-down\:facing\:parabola\:of\:the\:form}\:\\y=ax^2+bx+c\:\mathrm{is}\:x_v=-\dfrac{b}{2a}\)
The equation is
\(y=x^2+4x-12\)
\(\textrm {Here }\\a = 1, b = 4, c= -12\\\\\)
\(So\; x_v, \textrm{ the x value of the vertex } = -\dfrac{4}{2\cdot \:1} = -2\\\\\textrm {Plug this value of x into the equation to find the y-value of the vertex}\\\)
\(y_v=\left(-2\right)^2+4\left(-2\right)-12\\\\\\y_v = 4 -8 - 12 = -16\\\\\)

The staple food of the Vedic Aryans was mainly composed of cereal grains, particularly barley and rice.
These grains were considered the most important crops and were used to make a variety of dishes including porridge, bread, and fermented drinks like beer.While milk and its products were also an important part of their diet, especially for the pastoral communities, they were not the primary staple food. Similarly, rice and pulses, vegetables, and fruits were also part of their diet but not as dominant as barley and rice.It is worth noting that the Vedic period, which spanned from around 1500 BCE to 500 BCE, marked the beginning of Indian civilization and is considered an important time in the development of Hinduism, which had a significant influence on the cultural and social practices of the Indian subcontinent.To know more about vedic age visit:
