Question
![In a simulation project, the time (in minutes) between
arrivals of customers to a post office is to be
modelled. The team collected the arrival data of 200
customers and arranged it to perform a x² goodness-
of-fit test in the table below. They checked the
histogram of the data and thought that the distribution
should be Normal with the estimated mean value
T = 124 min and standard deviation s = 15.50
min.
Calculate and fill the missing entries in the table
(Assume k = 8).
