Question

A sample has a mean of m = 90. if each score in the sample is multiplied by 5, then what is the mean for the new distribution?

Answer 1

In the sample has a mean of m=90 and each score in the sample is multiply by 5 and you want to calculate the mean for the new distribution, you only have to multiply the mean (m=90) by 5.

Then:

m= 90x5
m=450

Therefore, the answer is: The mean for the new distribution is 450 (m=450).
