Recent studies have allowed psychologists to establish definite links between specific foods and specific brain functions. For example, lecithin has been shown to increase the concentration of certain brain chemicals that help regulate memory and motor coordination. An experiment was conducted that involves two separate samples of newborn rats. The ten rats in the first sample are given a diet with standard amounts of lecithin. The five rats in the second sample are fed a special diet, which contains almost no lecithin. After 6 months, each rat is tested on a specially designed learning problem that requires both…

A survey was done on 28 students, and the distribution of total study hours per week is bell-shaped with a mean of 13 hours and a standard deviation of 3.1 hours. Use the Empirical Rule to answer the following questions. a) 68% of the students spend between 12.41 X hours and 13.58 x hours on Statistics each week. b) 95% of the students spend between 11.82 X hours and 14.7 X hours on Statistics each week. c) 99.7% of the students spend between 11.24 X hours and 14.76 X hours on Statistics each week.
