Suppose 207 subjects are treated with a drug that is used to treat pain and 40 of them developed nausea. Can you conclude that less than 25% of users develop nausea? Use the o: = 0.04 level. a. State the null and alternative hypotheses. H0: '?v ?v H1: '?v '?v \\u b. Find the critical value and sketch the rejection region. Sketch of Rejection Region: -3-2-IOI23-3-2-10123-3-2-10I23 Critical value(s): (If there are two critical values. list both values separated by a comma) c. Find the test statistic. d. Find the p-value. e. Decide: Select an answer v Hg. f. Conclusion: At 0: = 0.04 significance level. there Select an answer v enough evidence to conclude that less than 25% of users develop nausea. A survey organization sampled 59 households in a community and found that the mean number ofTV sets per household was 2.47. The standard deviation is 1.4.

A random sample of 31 of these stocks had a mean price of $29.42 with a standard deivation of $6.54. A stock market analyst predicted that the mean price of all Russell-2000 stocks would be $27. Can you conclude that the mean price differs from $27? Use the a = 0.03 level. a. State the null and alternative hypotheses. Ho : ? v ? v H1 : ? v ? v b.
