In a population of exam scores, a score of X 48

corresponds to z1.00 and a score of X 36

corresponds to z –0.50. Find the mean and standard

deviation for the population. (Hint: Sketch the

distribution and locate the two scores on your sketch.)

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.
