Question

5. (worth 16 points) Consider a test of H : μ-65 versus Ha μ > 65. The test uses σ-10, α-01 size of n 64. and a sample a. Describe the sampling distribution of Fassuming Ho is true. Mean (t)- Standard deviation (oz)- Shape: Sketch the sampling distribution of x assuming Ho is true is used as the test stat istic. Locate the rejection region on your graph from b. Specify the rejection region when x part a. C. Describe the sampling distribution of if μ-68. Mean (Hl,) Standard deviation (σ) = Shape p 68. On your graph of part a, sketch the sampling distribution of Fif d. Find the probability of failing to reject Ho if u is actually equal to 68. That is, find the probability of commiting a Type 2 error if μ is actually equal to 68, Shade the area corresponding to this probability on your graph.
