f a population is normally distributed with a mean 500 and

f a population is normally distributed with a mean = 500 and a standard deviation = 50, and a sample of 4 is selected, the proportion of sample means between 450 and 550 will __________ the proportion of individual values between 450 and 550.

A-Be less than

B-Be greater than\\

C-Be the same as

D-Not be comparable to.

Solution

If a population is normally distributed with a mean = 500 and a standard deviation = 50, and a sample of 4 is selected, the proportion of sample means between 450 and 550 will C-Be the same as the proportion of individual values between 450 and 550.
