If we were to conduct a hypothesis test to test if a population proportion of a certain event is 0.2 versus the alternative that it is greater than 0.2 and we sampled 100 people, what would the probability of a Type I Error be if we were to use the arbitrary decision rule to reject Ho if more than 30 units in the sample had the event (not the way we tested hypotheses in class)? What would the probability of...

In a question involving a hypothesis test having the population mean as the target parameter, you are given the sample size, n, the assumed population mean, the significance of the test, alpha, whether it is a right-tailed, left-tailed, or two-tailed test, and the result of the test (reject or do not reject the null hypothesis.) Show how you can use this information to find bounds on the sample itself. You may put in simple values for the information given if...
