A student wishes to see if at her school the proportion of underclassmen who do not have have a job is greater than the proportion of upperclassmen who do not have have a job. To test her claim she randomly selects 257 underclassmen 55 did not have a job. She then randomly selects 288 upperclassmen and out of them 45 did not have a job. Test her claim at a=0.10 to see if she was right. Let underclassmen be sample 1 and upperclassmen be sample 2. The correct hypotheses are: Ho: P1 HA P1 O Ho: P1 HA P1 P2 P2(claim) P2 P2(claim) O Ho: P1 = P2 HA: P1 The p-value is: P2(claim) Since the level of significance is 0.10 the critical value is 1.282 The test statistic is: (round to 3 places) (round to 3 places)
