A nutrition 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 asks each person to 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 = 26 with SS = 960. In the general population, the standardized test is known to have a mean of mue, = 20.

a. Do the sample data support the conclusion that the Memory Booster has a significant effect? Test with a = .05.
