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, and Nyberg, 2004). In
a typical study, a researcher obtains a sample of n = 16 participants and has each person take the 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 from the test
form a normal distribution with a mean of p = 50
and a standard deviation of 6 = 12. The sample of research participants had an average of M = 54.
1. Assuming a two-tailed test, state the null hypothesis in a sentence that includes the two variables being examined.
