Question

The state of California has a mean annual rainfall of 22 inches, whereas the state of New York has a mean annual rainfall of 42 inches. Assume that the standard deviation for both states is 8 inches. A sample of 30 years of rainfall for California and a sample of 45 years of rainfall for New York has been taken. If required, round your answer to three decimal places.

(a)

Show the sampling distribution of the sample mean annual rainfall for California.

	E(x)	σ_x̄
California

(b)

Show the sampling distribution of the sample mean annual rainfall for New York.

	E(x)	σ_x̄
New York

(c)

In which of the preceding two cases, part (a) or part (b), is the standard error of x smaller? Why?

The standard error is for New York because the sample size is than for California.

The state of California has a mean annual rainfall of 22 inches, whereas the state of New York has a mean annual rainfall of 42 inches. Assume that the standard deviation for both
states is 8 inches. A sample of 30 years of rainfall for California and a sample of 45 years of rainfall for New York has been taken. If required, round your answer to three decimal
places.
(a) Show the sampling distribution of the sample mean annual rainfall for California.
