Question

A cable TV company was interested in making its operation more efficient by cutting down on the distance between service calls while still maintaining at least the same level of service quality. A treatment group of 18 repairpersons was assigned to a dispatcher who monitored all the incoming requests for cable repairs and then provided a service strategy for that day’s work orders. A control group of 18 repairpersons was to perform their work in a normal fashion—that is, by providing service in roughly a sequential order as requests for repairs were received. The average daily mileages for the 36 repairpersons are recorded in the table below.

What are the populations of interest in this study?

What is the level of significance of your test?

Is there significant evidence that the treatment group had a smaller average daily mileage than the control group? Use α = 0.05.

3. A cable TV company was interested in making its operation more efficient by cutting down on
the distance between service calls while still maintaining at least the same level of service quality.
A treatment group of 18 repairpersons was assigned to a dispatcher who monitored all the
incoming requests for cable repairs and then provided a service strategy for that day's work orders.
A control group of 18 repairpersons was to perform their work in a normal fashion-that is, by
providing service in roughly a sequential order as requests for repairs were received. The average
daily mileages for the 36 repairpersons are recorded in the table below.
a. What are the populations of interest in this study?
b. What is the level of significance of your test?
c. Is there significant evidence that the treatment group had a smaller average daily mileage
than the control group? Use a =
0.05.
