A) Give the null and alternative hypothesis for the test.
B) If you wish your probability to be of (erroneously) deciding that mu>30, when in fact =30, to equal 0.05, what is the value of alpha for the test?
C) Glance at the data and use your intuition to decide whether the sample mean, 30.9 implies that mu>30 . (Do not conduct the statistical test). Now test the null hypothesis. Do the data provide sufficient evidence to indicate that mu >30? Test using alpha =0.05.
2) Refer to the problem above. Suppose that you wish to detect a value of mu that differs from 30; that is, a value of mu either greater or less than 30. State the null and alternative hypothesis for the test.
