A plan for an executive travelers' club has been developed by an airline on the premise that 5% of its current customers would qualify for membership. A random sample of 500 customers yielded 45 who would qualify. (a) Using this data, test at level 0.01 the null hypothesis that the company's premise is correct against the alternative that it is not correct. State the appropriate null and alternative hypotheses. H0: p ≠ 0.05 Ha: p < 0.05 H0: p = 0.05 Ha: p > 0.05 H0: p = 0.05 Ha: p ≠ 0.05 H0: p ≠ 0.05 Ha: p = 0.05 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) z = P-value = State the conclusion in the problem context. Reject the null hypothesis. There is not sufficient evidence to conclude that the company's premise is incorrect. Do not reject the null hypothesis. There is not sufficient evidence to conclude that the company's premise is incorrect. Reject the null hypothesis. There is sufficient evidence to conclude that the company's premise is incorrect.
