Answer: Graph D

<u>Step-by-step explanation:</u>

Look at each graph to see where it cosses the x-axis. These are called; x-intercepts, solutions, zeros, and roots. All of these terms mean the same thing.

graph A) x-intercepts are: -2, -1, and 4

graph B) x-intercepts are: -2, -1, and 4 (it is the same graph as A)

graph C) x-intercepts are: -2, 1, and 4

graph D) x-intercepts are: -4, 1, and 2

The given solutions are -4, 1, and 2 so the correct graph is D.

A simple random sample of size n=10 is obtained from a population that is normally distributed with a mean of 40 and a standard

Eva8 [605]

Yes, the sampling distribution is normally distributed because the population is normally distributed.

A sampling distribution is a chance distribution of a statistic obtained from a larger variety of samples drawn from a specific populace. The sampling distribution of a given population is the distribution of frequencies of a variety of various outcomes that would probable occur for a statistic of a populace.

A sampling distribution is a probability distribution of a statistic this is obtained via drawing a huge variety of samples from a particular populace. Researchers use sampling distributions so that you can simplify the technique of statistical inference.

Solution :

mean = μ40

standard deviation σ σ= 3

n = 10

μx = 40

σ x = σ√n = 3/√10 = 0.9487

μ x = 4σ\x = 0.9487

σx = 0.9487

Yes, the sampling distribution is normally distributed because the population is normally distributed.
