a. Test the claim that the contents of cans of diet soda have weights with a mean that is less than the mean for the regular soda. What are the null and alternative hypotheses? H05P1=P2 H05P1P2 H15P1>P2 H15P1P2 H15P1P2 H05P1P2 H05P1p2 H15P1PZ The test statistic, t, is - 2.16'. (Round to two decimal places as needed.) The Pvalue is 0.018'. {Round to three decimal places as needed.) State the conclusion for the test. Reject H0. There is not sufficient evidence to support the claim that students taking nonproctored tests get a higher mean score than those taking proctored tests. Reject H0. There is sufficient evidence to support the claim that students taking nonproctored tests get a higher mean score than those taking proctored tests. " Fail to reject H0. There is not sufficient evidence to support the claim that students taking nonproctored tests get a higher mean score than those taking proctored tests. Fail to reject H0. There is sufficient evidence to support the claim that students taking nonproctored tests get a higher mean score than those taking proctored tests. b. Construct a condence interval suitable for testing the claim that students taking nonproctored tests get a higher mean score than those taking proctored tests. 19.87' l12 H13P1
