A study was done on proctored and nonproctored tests. The results are shown in the table. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Protored Nonprotored ???? 1 ???? 1 2 ???? 2 n 35 40 X ???? 86.02 91.38 S 11.55 25.31 Test the claim that students taking nonproctored ests get a higher mean score than those taking proctored tests. Use a significance level of = 0.07 ???? = 0 . 0 7 . What is the managerial decision? There is sufficient evidence to support the claim that students taking nonproctored tests get a higher mean score than those taking proctored tests. None of these options There is insufficient evidence to support the claim that students taking non proctored tests get a higher mean score than those taking proctored tests There is insufficient evidence to support the claim that students taking non proctored tests get a different mean score than those taking proctored tests There is sufficient evidence to support the claim that students taking non proctored tests get a different mean score than those taking proctored tests
