Suppose a researcher is interested in a new treatment plan for CD4 cell count in immune-compromised patients with HIV. In order to investigate the new drug, the researcher gathers a group of 55 individuals with a mean CD4 count of 300 cells/mm3 after treatment with a standard deviation of 25.1. Test the hypothesis that the mean CD4 count goal is not 292 cells/mm3. Perform a two-way directional test, complete the 5 step process and calculate the appropriate confidence interval. (Use an alpha level of 0.01) H0:u= (Example answer ###) Ha:u ≠ (Example answer ###) Ztest= (Example answer #.##) p-value= (Example answer .###) Confidence Interval= (Example answer ###.#,###.#) Fail to reject or Reject the H0 (Example answer Fail to reject or Reject)
