In testing a new drug, we obtained the following results:
Placebo | Drug A | Drug B | Drug C |
---|---|---|---|
6 | 4 | 6 | 7 |
3 | 3 | 3 | 6 |
5 | 1 | 4 | 5 |
3 | 1 | 3 | 4 |
3 | 1 | 4 | 3 |
Run the ANOVA and fill in the summary table with the results obtained:
SS | df | MS | F-ratio | p-value | |
Between | 3 | ||||
---|---|---|---|---|---|
Within | 16 | ||||
TOTAL |
19 |
(Report P-value & F-ratio accurate to 3 decimal places and all other values accurate to 2 decimal places.)
What conclusion can be drawn at the 0.01 significance level?
A) The various drugs have results that are statistically different.
B)The various drugs do not have results that are statistically different.
