A typical test performed by the FDA is the following: The weights of a random sample of five people are recorded before they are introduced to the liquid protein diet. The five individuals are then instructed to follow the liquid protein diet for 3 weeks. At the end of this period, their weights (in pounds) are again recorded. The results are listed in the table. Let 1 be the true mean weight of individuals before starting the diet and let 2 be the true mean weight of individuals after 3 weeks on the diet.
weight before in order from Person 1 to 5:
149, 194, 187, 196, 203
weight after in order from Person 1 to 5:
142, 189, 184, 190, 199
Summary information is as follows: = 5, sd = 1.58.
Test to determine if the diet is effective at reducing weight. Use = .10.
Report just the p-value below. Do the problem in SPSS. Assume this is a one-tailed test (testing weight loss). Report the p-value in the following format: 0.### (that is, three decimal places and a 0 in front of the decimal).
