Thus far, the following values for the ANOVA table have been determined. Use these to find the values for MSTR and MSE, rounding to three decimal places. Source of Sum of Degrees of Mean F Variation Squares Freedom Square MSTR = SSTR k - 1 Treatments SSTR = 2,021.400 k - 1 =3 2,021.400 SSE MSE = NT - K Error SSE = 4,559.004 nT - K = 36 4,559.004
