If an analysis of variance is used for the following data,what would be the effect of changing the value of M₂ to 25? Sample Data A)Increase SS_between and increase the size of the F-ratio M₁ = 10 M₂ = 20 B)Increase SS_between and decrease the size of the F-ratio SS₁ = 90 SS₂ = 70 C)Decrease SS_between and increase the size of the F-ratio D)Decrease SS_between and decrease the size of the F-ratio
