A sample of calls made to the customer service departments at
two publishers is taken, and the number of minutes spent on hold is
recorded. Results are shown in the table. Both populations of
hold-times are normally distributed.
Publisher C
n=32
x-bar=36.1 min.
s= 4.5 min.
Publisher D
n= 28
x-bar=45.7 min.
s= 7.3 min.
a. Use formula/chart to test the claim that the standard
deviation in hold-time is the same at both publishers. Use 0.05
significance and the critical...
