A researcher is evaluating customer satisfaction with the service and coverage of two phone carriers. Each individual in a sample of n=16 uses one carrier for two weeks and then switches to the other. Each participant then rates two carriers. The following table presents the results from the repeated-measures ANOVA comparing the average ratings. Fill in the missing values in the table. (Hint: Start with the df values.) Source SS df MS Between treatment ------ ------ 8 F=____ Within treatment ------ ------ Between subjects ------ ------ Error 60 ------ ------ Total 103 ------

16. A pharmaceutical company has developed a drug that is expected to reduce hunger. To test the drug, two samples of rats are selected with n = 20 in each sample. The rats in the first sample receive the drug every day and those in the second sample are given a placebo. The dependent variable is the amount of food eaten by each rat over a 1-month period. An ANOVA is used to evaluate the difference between the two sample means and the results are reported in the following summary table. Fill in all missing values in the table. (Hint: Start with the df column.) Source SS df MS Between treatments 20 F = 4.00 Within treatments Total
