HUESLIUH '5 U! \"1* oHO o o W\" ' 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 following 95% confidence interval was computed for the difference in mean scores of the two groups. Interpret the 95% confidence interval. The Condence Interval: ( - 0-42. - 0-05) M1 = the average test score of ginkgo supplement patients for F1 - \"2 )52 = the average test score of non ginkgo patients 1. We are 95% condent that there is no statistically significant difference in the average memory score between patients who received ginkgo and those who received the placebo. O 2. We are 95% condent that the average memory score for patients who received ginkgo is lower than the average memory score for those who received the placebo. O 3. We are 95% condent that the average memory score for patients who received ginkgo is higher than the average memory score for those who received the placebo. O 4. None of these is correct
