A Mail-Order Business Prides Itself in Its Ability to Fill

question 80

Short Answer

A mail-order business prides itself in its ability to fill orders in less than six calendar days, on average. Periodically, the operations manager selects a random sample of customer orders and determines the number of days required to fill the orders. On one occasion when a sample of 39 orders was selected, the average number of days was 6.65 with a population standard deviation of 1.5 days. What is the critical value for α = .10 when using the critical value rule to test the hypothesis that the time to fill orders is less than 6 days?
