The z score for the normal distributed data can be given as,
The mean value of the scores of history class is,
The standard deviation value of the scores of history class is,
Here, the test score of the Opal’s is 72. Thus the z score for her test score can be given as,
Hence, the value of z score for the history class test of Opal’s test score is negative one (-1).
