Question

A sale representative for a publishing company recorded the following numbers of client contacts for the 36 days that he was on the road in the month of May. Use the given data to construct a grouped frequency distribution using Rule 1. NOTE: Attach only 1 table

1. Rule 1. To determine the number of classes is to use the smallest positive integer k such
that 2* 2 11, where n is the total number of observations. Using Formula 2-1 we can obtain
the ideal class interval.
Suggested Class Interval=
Range
HV - LV
(Formula 2-1)
Numbe of Classes
k
where: HV =Highest value in a data set
k = number of classes
LV. = Lowest value in a data set
i = suggested class interval
