Homework Answers
We know that, the mean of random variable Z is 0. So we have to sorting given z scores according to how far from 0.
Therefore, sorted z scores are,
0, -0.25, +0.29, +0.58, -0.72, -0.83, +0.91
That is,
E, C, A, D, B, F, G
Add Answer to:
sort the following z-scores according to their distance from the
mean.
A= +.29
B= -.72
C=...
