A hypothesis test is to be performed. Determine the null and alternate hypotheses. In 1994 , the average duration of long-distance telephone calls originating in one town was 7.6 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 1994 mean of 7.6 minutes. H0 : =μ7.6 minutes H1 : <μ7.6 minutes H0 : =μ7.6 minutes H1 : ≠μ7.6 minutes H0 : =μ7.6 minutes H1 : >μ7.6 minutes H0 : ≠μ7.6 minutes H1 : =μ7.6 minutes
