A pharmaceutical company has developed a drug that is expected to reduce hunger.  To test the drug, three samples of rats are selected with n=10n=10 in each sample.  The first sample receives the drug every day.  The second sample is given the drug once a week, and the third sample receives no drug at all (the control group).  The dependent variables is the amount of food eaten by each rat over a 1-month period.  These data are analyzed by an ANOVA, and the results are reported in the following summary table.  Fill in all missing values in the table.  (Hint:  Start with the df column.)

Use the =FDIST() function in Excel to locate the p-value for this ANOVA:
p-value = 
Report p-value accurate to at least 6 decimal places.

If you use a significance level of α=.05α=.05, what would you conclude about these treatments?
