Example 2
Locate the z-value that corresponds to a PE score of 39 given that u = 45 and o = 6.
Step
Solution
1. Use the computing formula for finding z-
scores of population data.
2. Check the given values. The z-score in
question locates X in a population.
H= 45, o = 6 and X = 39.
3. Substitute the given values in the
computing formula.
|4. Compute the z-value.
39 – 45
z=
6
-6
=-1
6.
Thus, the z value that corresponds to the raw
score 39 is -1 in a population distribution.
With respect to the mean, the score 39 is below the population mean. We can also say that the score 39 is below average.

Performance Task!
Suppose you have the population values of 50 and 80 and that their corresponding z-scores are -1 and 2,
respectively. It is possible to determine the population's mean and standard deviation? If so, what are these value
If not, explain why it is impossible.
