1. In an ANOVA problem involving three treatments and 19 observations per treatment, SSE = 648. The MSE for this scenario is _______.

		12
		54
		29.5
		216

2. The following is the information for a completely randomized experimental design involving four treatments, where 20 observations were recorded for each treatment for a total of 80 observations. SST = 258 (Sum of Squares Between Groups); SS Total = 1,032 (Sum of Squares Total). The computed value of F, or the test statistic, is ________.

		8.44
		0.25
		20.0
		16.0

3. We test for a hypothesized difference between two independent population means: H₀: ₁ = ₂. The population standard deviations are unknown but assumed equal. The number of observations in the first sample is 18 and 15 in the second sample. How many degrees of freedom are associated with the critical value?
