1) Fill in the blanks
		response variable =
		factor =
		n = number of observations =
		p = number of treatments =
		overall mean =
			Drug A	Drug B	Drug C
		sample mean
Totalvariation in the data (SSTO)=
Variation caused because of drugs (SST) =
Variation caused by the samples (SSE) =
2) Fill in the ANOVA table(alpha=0.05)
Source of Variation	SS	df	MS	F	p-value	F-critical

Total
3) Based on your Anova table,write down the conclusion about Null hyphothesis (H0:µA=µB=µC)
	If you reject Null, what does that mean? Write itin once sentence.
4) Build TUKEY SIMULTANOUS 95%confidence intervals for the following:
		Tukey Simultamous C.I	µA-µB	µA-µC	µB-µC
		Point Estimate
		Standard error
	df = p and n-p ----->	q alpha
		Margin of error
		Lower Limit
		Upper Limit
5) Build Individual 95%confidence intervals for the following:
		Individual C.I	µA-µB	µA-µC	µB-µC	µA
		Point Estimate
		Standard error
	df = n-p ---- >	talpha/2
		Margin of error
		Lower Limit
		Upper Limit
6)Based on the answers on parts 4 and 5, write down your conclusionsabout which drug beats which drug?
7) Create the MegaStat outputand fill in the blanks by using the post-hoc analysis of MegsaStatoutput:
	What is the p-value of comparing drug A and B
	What is the p-value of comparing drug C and B
	Did we findevidence that the effects of drugs B and C on pain relief aredifferent from eachother?
