    The production line that packages boxes of raisins at a snack food manufacturer will be conisdered operating properly if the average weight of the boxes of raisin is 3.5 ounces with a standard deviation of 0.3 ounces. A random sample of 20 boxes showed an average weight of 3.30 ounces. Answer questions 4 and 5 based upon this information.

    A. Provide the null and alternative hypthosis to determine if the production line is operating properly.

    B. What additional assumption is needed before we can perform a test to determine whether the production line is operating properly?

    C. State the value of the correct rejection region for alpha = 0.05.
    Lower Limit =
    Upper Limit =

    D. State the value of the correct rejection region for alpha = 0.01.
    Lower Limit =
    Upper Limit =
