Conduct a hypothesis test for the following scenarios. You may compute the p-value either by simulation or test-statistic 1) 2) 3) at least one problem must be done by test-statistic conversion at least one problem must be done by simulation simulation should involve at least 10,000 trials. The grading scheme is as follows: Identify and describe the parameter of interest. State the null and alternative hypotheses, using correct notation. Be specific with your parameters. 2pts State the value of the...
