Answer 1

C. The number of crackers in the supervisor's bag is 1 standard deviation to the right of the mean.

Explanation:

Data

• the mean number of crackers in each bag is 22

• the standard deviation is 2

mean + standard deviation = 22 + 2 = 24, that is, 1 standard deviation to the right of the mean (the addition is to the right, the subtraction to the left).
