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
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.
Cannot sketch on the posts.
Use same processes as indicated on my response to your previous post.
