7) A mаil-оrder business prides itself in its аbility tо fill custоmers' orders in six cаlendar days or less on the average. Periodically, the operations manager selects a random sample of customer orders and determines the number of days required to fill the orders.

He will assume that the average number of days to fill customers' orders is six or less unless the data suggest strongly otherwise. Establish the appropriate null and alternative hypotheses.
