Answer:

The answer to this question is within 2 stabdard deviations

Step-by-step explanation:

to get the score of 85 you got to add the deviation value to the mean whuch creates the deviation. do that multiple times and you get a multiple deviation

72+8=80+8 is 88

88 is greater than 85 so a test score of 85 is within 2 standard deviations of the mean
