Textbook Problem

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.)

To determine

**To find:** The missing values in the ANOVA summary table given in the question.
