A production line operation is tested for filling weight accuracy using the following hypotheses.

Hypothesis       Conclusion and Action
H 0:  = 16         Filling okay, keep running
H a:     16       Filling off standard; stop and adjust machine

The sample size is 36 and the population standard deviation is  = 0.8. Use  = .05. Do not round intermediate calculations.

  1. What would a Type II error mean in this situation?
    Concluding that the mean filling weight is not 16 ounces when it actually isConcluding that the mean filling weight is 16 ounces when it actually isn'tItem 1
  2. What is the probability of making a Type II error when the machine is overfilling by .5 ounces (to 4 decimals)?

  3. What is the power of the statistical test when the machine is overfilling by .5 ounces (to 4 decimals)?

A production line operation is designed to fill cartons with laundry detergent to a mean weight of 64 ounces. A sample of cartons is periodically selected and weighed to determine whether underfilling or overfilling is occurring. If the sample data lead to a conclusion of underfilling or overfilling, the production line will be shut down and adjusted to obtain proper filling. (a) Formulate the null and alternative hypotheses that will help in deciding whether to shut down and adjust the...
