QUESTION 3 Researchers used ANOVA to evaluate the mean differences in cholesterol concentration among five smoking groups: never, former light, former heavy, current light, and current heavy. The analysis produces SSW (sum of squares within groups) = 150, SSB (sum of squares between groups) - 320. For this analysis, what is the MSB (mean square between groups)? 1. 150/5 2.150/4 3.320/5 4.32074
