68h store in the mall is selling "Memory Booster" which is a concoction of herbs and minerals that is intended to improve memory performance. To test the effectiveness of the herbal mix, a researcher obtains a sample of n= 16 people and has each person take the suggested dosage each day for 4 weeks. At the end of the four-week period, each individual takes a standardized memory test. The scores from the sample produced a mean of M = 36 with a sample variance of s² = 84. In the general population, the standardized test is known to have a mean of u =30. This study is to be analyzed using a O a. repeated measures t-test Ob. one sample z-test OC F-test d.one sample t1-test
