Truth p~ Two samples are drawn to test the hypothesis,Ho: p= 0.5us H4: p0.5. One sample has size n 250 and the other has size n=125. Both samples yield the same sample proportion of 0.4.Consider the statement:The samples will produce the different p-values for the hypothesis test above.. Is this statement always true, sometimes true or never true?

5. Consider testing the hypothesis Ho : p = 0.5 vs. Ha : pメ0.5 using two tests, both at the same level of significance. The first test, Tl, requires a sample of size 45 while the second test, T2, requires a sample of size 100 for their power functions to be equal at the particular alternative p 0.3. What is the efficiency of T2 relative to T1? Ffficiency (ARE) of test Tı relative to test T2 is 0.3 and the

5. We wish to conduct a hypothesis test of the form Ho : μ1-2-0 vs Ha : μί-μ2 > 0. Both populations are assumed normal with equal variance and samples are assumed independent. We draw 15 observations for the first sample and 17 observations for the second sample. State the distribution of the test statistic for this test.
