The empirical rule states that in a normal distribution,
68% of data is within 1 std deviation of the mean
95% of data is within 2 std deviation of the mean
99.7% of data is within 3 std deviation of the mean
In this case 95% of the cases would be within two std deviations of the mean
mean - 8 and mean + 8
72 - 8 = 64 and 72 + 8 = 80
then 95% of the scores are between 64% and 80% on the test.
Step-by-step explanation:
<em>option</em><em> </em><em>D </em><em>is </em><em>correct</em><em>,</em>

-2.1 - (5.9 + 3.7)
Both equal -11.7 so that is the correct option.
