Reference no: EM13120471

The Store kept track of the number of paying customers it had during the noon hour each day for 100 days. The following are the resulting statistics rounded to the nearest integer: Mean = 95 Median = 97 Mode = 98 First quartile = 85 Third quartile = 107 Midrange = 93 Range = 56 Standard deviation = 12 For how many of the 100 days was the number of paying customers within three standard deviations of the mean ? Explain how you determined your answer.
