Prefs Done We want to test Ho:M= 1.5 vs. Hall # 1.5 at a = 0.05. A 95% confidence interval for u calculated from a random sample is (1.4, 3.6). Based on this finding we can support the following conclusion Cannot make any decision at all because the distribution of the population is unknown. Cannot make any decision at all because (1.4, 3.6) is only a 95% confidence interval for J. . Fail to reject HO . Reject HO . Cannot make any decision at all because the value of the test statistic is not available e p. 11 of 15 .

Prefs Done 10. A tobacco company is investigating if a new treatment is effective in reducing the damage caused by a tobacco virus. Eleven plants were randomly chosen. On each plant, one leaf was randomly selected, and one half of the leaf (randomly chosen) was coated with the treatment, while the other half was left untouched (control). After two weeks, the amount of damage to each half of the leaf was assessed. For purposes of comparing the damage, which of the following is the appropriate inference procedure? . Paired t test for a mean difference Two-sample z test for a difference in proportions Two-sample t test for a difference in means Two-sample t test for a difference in proportions Two-sample z test for a difference in means e p. 12 of 15 . 3:37 PM Type here to search O 4/18/2021
