The answer to your question is a^32
Answer:
Alpha (α) is used to measure the error for decisions concerning true null hypotheses, while beta (ß) is used to measure error for decisions concerning false null hypotheses.
Step-by-step explanation:
Suppose we have events X and Y.
1. If it is said that X equals Y, when X is actually not equal to Y, α is used in this case, the null hypotheses.
2. If X is said to not be equal to Y, when X is actually equal to Y, β is used in this case, the false null hypotheses.
In order to find the area of the semicircle, or the shaded region, we just have to find the area of the entire circle and divide it by 2. The formula for the area of a circle is

. With the given diameter of 12, we can deduce that the radius is 6.
Area of Semicircle = (

/2)
Area of Semicircle = (3.14 x 36/2)
Area of Semicircle = (3.14 x 18)
Area of Semicircle = 56.52

Hope this helps!
Answer:
A
Step-by-step explanation:
The answer is A as the height starts at 36 and decreases by 9 inches vertically every 12 inches it goes down horizontally.
If you turn this into an equation, you get y = -(9/12)x+36.
Then, you simplify this to y = -(3/4)x+36, which is A.
Answer:
b. Applicants for the federal funding
Step-by-step explanation:
Sampling
This is a common statistics practice, when we want to study something from a population, we find a sample of this population.
For example:
I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected New York state residents wheter they are Buffalo Bills fans, and expand this to the entire population of New York State residents, which is the population of interest.
In this question:
She takes a sample of applicants for the federal funding from the US, which means that the population of interest is all applicants for the federal funding in the US. The correct answer is given by option b.
