<PRE><B>Question 468295</B>
A coin-operated drink machine was designed to discharge a mean of 9 ounces of coffee per cup. Suppose that we want to carry out a hypothesis test to see if the true mean discharge differs from 9. State the null hypothesis H(subscript)0 and the alternative hypothesis H(subscript)1 that we would use for this test.
-------------
Ho: u = 9
Ha: u is not equal to 9

----
Note: Keep in mind that equality must ALWAYS
be a part of Ho, no matter what the claim is.
The claim may be in Ho or it may be in Ha.
