Based on the data below, answer these questions.RaceNMeanBlack11325.39White90422.99Other14423.87All Groups1,16123.33Calculate the value of the between group sum of squares (SSB).RaceY bar for each groupTotal meanGroup mean â Total meanSquare of the differenceThe number of casesNk*Square of the differenceBlackWhiteOtherSum up=Calculate the degrees of freedom for the between group sum of squares. Then, use this quantity to calculate the mean square betweenIf the F statistic calculated for these data is 8.49, what is the value of the mean square within n?Following answer of #3, calculate the within group sum of squares and the number of degrees of freedom for the within group sum of squares.Imagine you are interested in whether there is a significant difference between the mean age of marriage across educational groups. If the critical value for an F statistic of 8.49 is 2.99, are these results statistically significant or not
