Statistics problems

In this exercise, test Ho : p = 0.5 vs Ha : p > 0.5, with p = 0.58 for different sample sizes. In parts (a) and (b), use StatKey or other technology to find the p-value. Click here to access StatKey. (a) p = 29 50 = 0.58 Round your answer to two decimal places. p-value = i Are the results significant at the 5% level? No (b ) p = 290 500 = 0.58 Round your answer to four decimal places. p-value =Ho : P1 = P2 VS Ha : P1 > P2, with p1 - P2 = 0.45 - 0.30 = 0.15 for different sample sizes. In parts (a)-(c), use StatKey or other technology to find the p-value. Click here to access StatKey. (a) p1 = = 0.45 and P2 = 6 20 20 = 0.30 Round your answer to two decimal places. p-value = Are the results significant at the 5% level? (b ) P 1 = 90 - = 0.45 and p2 = 60 200 200 = 0.30 Round your answer to three decimal places. p-value = iV 900 = 0.45 and p2 600 (c) P1 = A 2000 = 2000 = 0.30 Round your answer to three decimal places. p-value = HI Are the results significant at the 5% level? VIn this exercise, we are conducting many hypothesis tests to test a claim. Assume that the null hypothesis is true. If 300 tests are conducted using a significance level of 1%, approximately how many of the tests will incorrectly find significance? i of the tests will find significance.In this exercise, we are conducting many hypothesis tests to test a claim. Assume that the null hypothesis is true. If 1100 tests are conducted using a significance level of 5%, approximately how many of the tests will incorrectly find significance? i of the tests will find significance
