Classify the hypothesis test as two-tailed, left-tailed, or right-tailed. At one school, the average amount of time that tenth-graders spend watching television each week is 21.2 hours. The principal introduces a campaign to encourage the students to watch less television. One year later, the principal wants to perform a hypothesis test to determine whether the average amount of time spent watching television per week has decreased from the previous mean of 21.2 hours. O Right-tailed O Left-tailed O Two-tailed

A hypothesis test is to be performed. Determine the null and alternate hypotheses. In 1991, the average duration of long-distance telephone calls originating in one town was 7.1 minutes. A long-distance telephone company wants to perform a hypothesis test to determine whether the average duration of long-distance phone calls has changed from the 1991 mean of 7.1 minutes. Ho:u= 7.1minutes H:µ > 7.1minutes Ho:u = 7.1minutes H:u + 7.1minutes Ho:u = 7.1minutes = 7.1 minutes Ho:u = 7.1minutes H:u<7.1minutes
