Answer #1

The given ANOVA Table is completed as follows:

Source Sum of Squares df Mean Square F
Between Groups 2376.8 3 - 1 = 2 2376.8/2=1188.4 21.0659
Within Groups 846.2 18 - 3 = 15 846.2/15=56.4133
Total 3222.9 18 - 1 = 17

Correct option:

The three treatment groups differ in SBP.

Explanation:

For Degrees of Freedom (2,15) and \alpha = 0.05, critical value of F = 3.682. Since calculated value of F is greater than critical value of F, reject null hypothesis and conclude that the three treatment groups differ in SBP..
