The corner convenience store kept track of the number of paying customers it had during the noon hour each day for 100 days. the resulting statistics are rounded to the nearest integer: mean = 95 median = 97 first quartile = 85 third quartile = 107 midrange = 93 range = 56 standard deviation = 12 assume that the data are already ordered. a) on how many days were there between 85 and 107 paying customers during the noon hour? b) what was the smallest and greatest number of paying customers during any one noon hour? c) for how many of the 100 days was the number of paying customers within three standard deviations of the mean?
