An airline company recently boasted about its 73% customer satisfaction rate. A corporate watchdog group believes that this percentage is greatly exaggerated, and the real percentage of satisfied customers is lower than 73%. The group randomly surveyed 894 recent customers of this airline and found that only 646 reported being satisfied with the airline . Using alpha = 0.02 test the hypothesis that the proportion of satisfied customers of this airline is less than 73%. Use the critical value method . State the null and alternative hypothesis for this test. H 0 : boxed ? V Determine if this test is left-tailed, right-tailed, or two-tailed. two-tailed right-tailed left-tailed Should the standard normal () distribution or Student's (t) distribution be used for this test? The standard normal () distribution should be used The Student's distribution should be used Determine the critical value(s) for this hypothesis test. Round the solution(s) to two decimal places. If more than one critical value exists, enter the solutions using a comma-separated list. Determine the test statisticRound the solution to two decimal places. Determine the appropriate conclusion for this hypothesis test.
