Consider the following hypothesis test. Ho: H = 15 Hại H # 15 A sample of 50 provided a sample mean of 14.05. The population standard deviation is 3. (a) Find the value of the test statistic. (Round your answer to two decimal places.) (b) Find the p-value. (Round your answer to four decimal places.) p-value = (c) At a = 0.05, state your conclusion. Reject Ho. There is sufficient evidence to conclude that u # 15. Reject Ho. There is insufficient evidence to conclude that µ # 15. Do not reject Ho. There is sufficient evidence to conclude that u + 15. Do not reject Ho. There is insufficient evidence to conclude that u + 15.

Suppose a researcher is interested in a new treatment plan for increasing CD4 cell count in immune-compromised patients with HIV. In order to investigate the new drug, the researcher gathers a group of 48 individuals with a mean CD4 count of 317 cells/mm3 after treatment with a standard deviation of 24.6. Test the hypothesis that the mean CD4 count has increased above the goal of 275 cells/mm3. Write out your hypotheses and correctly interpret your pvalue. (Use an alpha level of 0.01)
