Question 3 of 4 Click For A Question 2 3 Submit Using ginkgo supplements to reverse memory loss has been touted by some people for centuries. Although many clinical studies have been made in recent years, these studies have not always come to the conclusion that ginkgo supplements do reverse memory loss. Suppose that a study was made in which 80 elderly adult patients were randomly and independently assigned to two groups of 40 each. The patients in Group A were given daily supplements of ginkgo and the patients in Group B were given a placebo. At the end of the treatment period each patient was scored on a memory test. Each score is a number from 1 to 10, with higher scores indicating better memory. Data was collected and the test statistic z* = 1.75 was computed. Find the p-value which corresponds to the test of hypotheses below. Ho M - M = 0 HA M-M20 1. p-value = 0.0802 2. p-value = 0.0610 3. p-value = 0.0401 4. p-value = 0.0704 M = the average test score of ginkgo supplement patients M2 = the average test score of non ginkgo patients
