Anormally distributed population has a mean of 250 pounds
anda standard deviation of 10 pounds. given n= 20, what is
theprobability that this sample will have a mean value between 245
and255?

0.9746

Step-by-step explanation:

Given : A normally distributed population has a mean of 250 pounds and a standard deviation of 10 pounds.

i.e.

Sample size : n= 20

Let sample mean values.

Then, the probability that this sample will have a mean value between 245  and 255 be

Hence , the probability that this sample will have a mean value between 245  and 255 is 0.9746 .
