A researcher conducted an experiment on the effects of a new multivitamin on energy level, with a control group (received nothing), a placebo group, and an experimental group (received the multivitamin). An energy inventory that provided a measure of energy level on a 50-point scale was used, where 50 indicated an individual who feels high levels of a lack of energy. The ANOVA summary table follows, together with the mean energy level score for each condition.

Source	df	SS	MS	F
Between groups		1,202.313
Within groups		2118.00		------
Total		3,320.313	------	------

Drug Condition	Mean	N
Control	36.26	15
Placebo	33.33	15
Multivitamin	24.13	15

a) Complete the ANOVA summary table.

b) Is f_obt significant at a = .05?

c) Perform post hoc comparisons if necessary.

d) What conclusions can be drawn from the F- ratio and the post hoc comparisons?

e) What is the effect size, and what does it mean?
