Question

A radio station wants to control the time allotted to unpaid public service commercials. If there are too many such commercials, the station loses revenue; if there are too few, the station loses points with the Federal Communications Commission. The target figure is an average of 1.5 commercial minutes per hour. A random sample of several one-hour segments of programming is taken.

(1)Use Minitab to conduct a test to see if the average number of commercial minutes per hour differs from 1.5 minutes. Report the value of the appropriate test statistic and the p-value.

Test Statistic Value = (rounded to 2 decimal places)
p-value =  (rounded to 3 decimal places; 4 for Minitab Express)

(2) What is your decision? Use α = 0.05.

O Reject Ho

O Do not reject Ho
