Dr. Kirtland (1) The figure below shows a randomization distribution for testing Ho : A = 50 vs Ha : A 0.45 for a population proportion along with 63 the sample data ? = 125 = 0.504. Use StatKey or other technology to generate a randomization distribution and calculate the p-value. p-value: (3) We are conducting many hypothesis tests to test a claim. Assuming the null hypothesis is true, approximately how many of the 200 tests, using a significance level of 5%, will incorrectly find significance? (4) For the situation described below, indicate whether it makes more sense to use a relatively large significance level (such as o = 0.10) or a relatively small significance level (such as a = 0.01). Testing to see if a large investment firm is participating in the illegal prac- tice of insider trading. If there is evidence, the Securities and Exchange Commission will file a lawsuit against them
