Asked by Tanyetta

On a standardized test, Phyllis scored 84, exactly one standard deviation about the mean. If the standard deviation for the test is 6, what is the mean score for the test?
Answered by PsyDAG
I assume you mean above the mean.

Z = (score-mean)/SD

Z = +1

Insert values and calculate.
