HT1) A research center claims that more than 65% of U.S. adults think that it is essential the United State continue to be a world leader in space exploration. In a random sample of 125 U.S. adults, 91 think that it is essential the Unites States continues to be a world leader in space exploration. At a = 0.05, is there enough evidence to reject the center's claim? a) Write out the null and alternative hypothesis: b) What sort of test is appropriate to test the claim? t-test for mean, µ z-test for mean, µ z-test for proportion, p c) Set up curve (draw tail(s) and label rejection region with the appropriate value):
