Total Sum of Squares = 776805.8 Sum of Squares for Income = 52493.15 Sum of Squares for Zonal Location = 540452.7 Sum of Squares for Income and Zonal Location = 36644.72 Sum of Squares for Errors = 147215.2 (c) Mean Squares for Income = 26246.6 Mean Squares for Zonal Location = 135113.2 Mean of Squares for Income and Zonal Location = 4580.59 (d) F statistics for Income = 10.69 p value for Income = 0.0001 F statistics for Zonal Location = 55.07 p value for Income = 0.0000 F statistics for Income and Zonal Location = 1.87 p value for Income = 0.0822 (e) As p value of Interaction b/w Income and Zonal Locations = 0.08 > 0.05, hence at 5% significance level, we dont have enough evidence to reject the null hypothesis. Therefore we can conclude that Interaction Effect is insignificant
