Q2) Although there is a popular belief that herbal remedies such as Ginkgo biloba and Ginseng may improve learning and memory in healthy adults, these effects are usually not supported by well-controlled research (Persson, Bringlov, Nilsson, & Nyberg, 2004). In a typical study, a researcher obtains a sample of n = 36 participants and has each person take herbal supplements every day for 90 days. At the end of the 90 days, each person takes a standardized memory test. For the general population, scores for the test are normally distributed with mu = 80 and 0 =18 and The sample of research participants had an average of M = 84. Identify the independent and dependent variables for this study Use the information above to conduct a two-tailed hypothesis test using . Be sure you complete all five steps of hypothesis testing and show your work/answers for each step. State your hypotheses using both words and statistical notation Calculate standard error Correct equation Correct value Determine the critical value Conduct hypothesis test Correct equation Correct value Comparison of obtained z and critical z Make a decision about rejecting/failing to reject the hypothesis Explicitly states “reject” or “fail to reject” Writes a 1-2 sentence conclusion interpreting the results Writes correct conclusion using statistical notation
