Scores were obtained from a hypothetical test A. Only 12 scores
from a large group in which the distribution of scores is
approximately normal are presented here.
75 61 93 84 11 50 36 42 57 76 46
70
Mean=58
SD=23
58.41667 23.00774
(1) What are the Z values for the score 42 and 75?
Homework Answers
Answer)
Z = (x - mean)/s.d
Given mean = 58
S.d = 23
For 42
Z = (42 - 58)/23 = -0.7
For 75
Z = (75 - 58)/23 = 0.74
