Hi. This question is coming from Modern Mathematical Statistics with Applications, Second Edition by

Jay L. Devore & Kenneth N. Berk. The question is #16, in section 9.2:

a. Ha: m > m0, df =15, rejection region t greater than or equal to 3.733

b. Ha: m

c. Ha: m does not equal m0, n is equal to 31, rejection region t is greater than or equal to 1.697 or t is less than or equal to -1.697

16 . Let the test statistic I have a t distribution when He is true . Give the significance level for each of the following situations a . Ha : M > MO of = 15 , rejection region 4 5 272 2 b . Ha : M 1697 ort 1 697
