Which of the following Z- SCORE values represents the location farthest
from the mean? - Answer- z = -2.00
For the population with u = 80 and o = 6, what is the Z - SCORE
corresponding to X = 68? - Answer- 2.00
For a population with u = 40 and o = 8, what is the X value
corresponding to z = 1.50? - Answer- 52
A population has u = 50. What value of 0 would make X = 55 a central,
representative score in the population? - Answer- o = 10
A population of scores has u = 80. In this population, a score of X = 86
corresponds to z = +2.00. What is the population standard deviation? -
Answer- 3
In a population of scores, X = 44 corresponds to z = +0.50 and X = 50
corresponds to z = +2.00. What are the values for the population mean
and standard deviation? - Answer- u = 42 and 0 =4
If an entire population with u = 60 and 0 = 8 is transformed into z = 8 is
transformed into z - scores, then the distribution of z-scores will have a
mean of ___ and a standard deviation of ____.- Answer- 0;1

A distribution with u = 55 and o = 6 // what value will be obtained for a
score of X = 58 from the original distribution? - Answer- X = 55
A sample of n = 20 scores has a mean of M = 45 and a standard
deviation of s = 8. In this sample, what is the z-score corresponding to X
= 57? z = - Answer- 1.50
A score that is 2 points higher than the sample mean has a z-score of z =
0.50, and a score of X = 44 has a z - score of - 1.00. What is the sample
mean?
- Answer- M=48
