A college recently advertised that 86% of its students graduate debt-free. A student advocacy organization thinks that the college's claim is unlikely. The organization collected a random sample of 1345 recent graduates from the college and found that 83% of the sample graduated without any student debt. Use significance level of 1% and employ the critical-value method to test the hypothesis that the proportion of all students from this college that graduate debt-free is different than 86%. State the null and alternative hypothesis for this test. OHp-0.86, H :p 0.86 O Hap0.86, H: p 0.86 OH p0.86, H: p=0.86 Determine the critical-value(s) for the hypothesis test. O-2.81, 2.81 O-2.58, 2.58 O-2.17, 2.17 02.58 Determine test statistic for the hypothesis test. O-2.46 O-3.37 0.3.17 O-1.86 Determine the appropriate conclusion for this hypothesis test. O The sample data provide sufficient evidence to reject the alternative hypothesis that the proportion of all students at the college that graduate debt-free is different than 0.36 and thus we conclude that the proportion of all students at the college that graduate debt-free is likely equal to 0.88. O The sample data do not provide sufficient evidence to reject the alternative hypothesis that the proportion o studen at the college that graduate debt-free is different than 0.86 and thus we conclude that the proportion of all students at the college that graduate debt-free is likely different than 0.86 The sample of all proportion not provide sufficient evidence to reject the null hypothesis that the proportion the college that graduate debt-free is 0.86 and thus we conclude that the lents at the college that graduate debt-free is likely equal to 0.86 O The sample data provide sufficient evidence to re the null hypothesis that the of all
