Question

corresponds to z��1.00 and a score of X � 36
corresponds to z � –0.50. Find the mean and standard
deviation for the population. (Hint: Sketch the

A sample consists of the following n � 6 scores: 2, 7,
4, 6, 4, and 7.
a. Compute the mean and standard deviation for the
sample.
b. Find the z-score for each score in the sample.
c. Transform the original sample into a new sample
with a mean of M � 50 and s � 10.
