After once again losing a football game to the college'ss arch rival, the alumni association conducted a survey to see if alumni were in favor of firing the coach. a simple random sample of 100 alumni from the population of all living alumni was taken. sixty-four of the alumni in the sample were in favor of firing the coach. let p represent the proportion of all living alumni who favor firing the coach
what is a 90% confidence interval for p? ( upper and lower limit to 4 decimal places)
suppose the alumni association wished to see if the majority of alumni are in favor of firing the coach. to do this they test the hypotheses h0: p = 0.50 versus ha: p > 0.50. what is the p-value for this hypothesis test? ( 4 decimal places)
suppose the alumni association wished to conduct the test at a 1% significance level. what would their decision be? based on that decision, what type of mistake could they have made?
