Extracted text: A hypothesis test is to be performed. Determine the null and alternate hypotheses. In 1993, the average duration of long-distance telephone calls originating in one town was 6.8 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 1993 mean of 6.8 minutes. Ho:u= 6.8minutes OH:u<6.8minutes ho:u="6.8minutes" h:µ="6.8minutes" ho="6.8minutes" h:u="">6.8minutes HoH=6.8minutes H:µ=6.8minutes
