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=9 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.) S.S. d.f. M.S. F Between 4.36 Within 3.71 TOTAL Use the =FDIST(∙) function in Excel or the pf(∙) function in R to locate the p-value for this ANOVA: p-value = Report answer accurate to at least 4 decimal places. If you use a significance level of α=.05, what would you conclude about these treatments? There is a significant difference between treatments These data do not provide evidence of a difference between the treatments

Question
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=9 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.)
| S.S. | d.f. | M.S. | F | |
|---|---|---|---|---|
| Between | 4.36 | |||
| Within | 3.71 | |||
| TOTAL |
Use the =FDIST(∙)
p-value =
Report answer accurate to at least 4 decimal places.
If you use a significance level of α=.05, what would you conclude about these treatments?
- There is a significant difference between treatments
- These data do not provide evidence of a difference between the treatments
