(10) The Corner Convenience Store kept track of the number of paying customers it had during the noon hour each day for the last 150 days. The following are the resulting statistics rounded to the nearest integer:mean = 94standard deviation (s) = 12median = 97first quartile (Q1) = 85mode (m) = 98third quartile (Q3) = 107range (R) = 56a)The Corner Convenience Store served what number of paying customers during the noon hours more often than any other number? Explain how you determined your answer.Answer: The Corner Convenience Store served 98 customers during the noon hours more often than any other number. Because mode means the most frequently number. b)On how many days was there between 85 and 107 paying customers during the noon hour? Explain how you determined your answer.Answer: Q1=85, Q2=107, The comprises of 50% or (107-85)=28 of the data set. (28*2)=56 or the range of the data set The smallest value of the data set= 69 the largest value=125. (150 Days/56)=2.68 days. Because 50% of the data lies between the first and third quartile (.50)*56=28*2.68 Days=75 days. So there was 75 days between 85 and 107 customers.#p#分页标题#e#

c)For how many of the 150 days was the number of paying customers within three standard deviations of the mean? Explain how you determined your answer.
