Question 354383: A coin-operated coffee machine made by BIG Corporation was designed to discharge a mean of 7.3 ounces ounces of coffee per cup. If it dispenses more that that on average, the corporation may lose money, and if it dispenses less, the customers may complain.
Believing that the mean amount of coffee dispensed by the machine, is less than 7.3 ounces, BIG plans to do a statistical test of the claim that the machine is working as designed. Technicians gather a random sample of fill amounts and find that the mean of the sample is 7 ounces and that the standard deviation is ounces.
Based on this information, answer the questions below.
What are the null hypothesis (H0) and the alternative hypothesis (h1) that should be used for the test?
In the context of this test, what is the type II error? A type II error is (rejecting or failing to reject), the hypothesis that the mean is (less than, less than or equal to, greater than, greater than or equal to, not equal to, equal to) 7, 7.3 or 0.3
Suppose that BIG decides not to reject the null hypothesis. What sort of error might it be making? Type I or Type II
