Answer:

a. between 24 and 30 minutes

Explanation:

Lower limit: = average time - standard deviation

                    = 27 - 3 = 24minutes

Upper limit: = average time + standard deviation

                      = 27 + 3 = 30minutes

Therefore,if  a customer were to receive the delivery within one standard deviation from the mean, he would get this pizza between 24 and 30 minutes
