Q.2.Consider the partial ANOVA table given in Table 1 below. The ANOVA table corresponds to a single-factor experiment with three treatments that were replicated 13, 92, and 59 times. Use the information in the table to answer the following questions:

Table 1: ANOVA Table

Source of Variation	Sum of Squares	DF	Mean Square	F Value Variance Ratio	P-value
Treatments		?	?	5.88	0.0034
Error	198442.24	?	?
Total	?	?

1. Fill in the missing entries in the ANOVA Table.
2. Estimate the standard deviation of the error term in the model.
3. Use the sample standard deviations given in Table 2 (below) to check the constant variance assumption. Is it reasonable to assume that each of the treatment groups has the same variance?

Table 2: Sample standard deviations

Treatment	Sample SD
A	29.74
B	35.24
C	38.85

1. Assuming all conditions underlying ANOVA are met, test the hypothesis of equal treatment means at the the=0.05 level. Show all five steps.
