1. Given the following sample information , test the hypothesis that the treatment means are equal at the 0.05 significance level:

Treatment 1	Treatment 2	Treatment 3
2	8	6
2	8	2
2	8	4
1	4	3
2	7	5
4	7	6
	9	3
	5	5
	5 9

a) What is the decision rule?

Reject H₀ if F > -----

b) Compute SST, SSE, and SS total.

SST=

SSE=

SS total =

c) Complete the ANOVA table.

e) State your decision regarding the null hypothesis.

Decision -------- H₀

f) If H₀ is rejected, can we conclude that treatment 2 and treatment 3 differ? Use the 95% level of confidence.

95% confidence interval is ----- -------

We can conclude that the treatments 2 and 3 are ------
