QUESTION 9

A.)

the distribution of the sample mean, , is approximately normal with mean    and standard deviation , as n gets large.

B.)

the distribution of the sample mean, , is approximately the same as the distribution of the original population or process, with mean    and standard deviation , as n gets large.

C.)

the distribution of the sample data is approximately normal with mean and standard deviation , as n gets large.

D.)

the distribution of the sample mean, , is approximately normal with mean    and standard deviation , as n gets large.

E.)

the distribution of the sample mean, , is approximately normal with mean    and standard deviation , as n gets large.

Explanation / Answer

According to the central limit theorem, the sampling distrbution will have the same mean as the population mean, mu, but the new standard deviation is sigma/sqrt(n).

Thus, it is OPTION E: the distribution of the sample mean, X , is approximately normal with mean mu and standard deviation signa/sqrt(n), as n gets large. [ANSWER, OPTION E]
