Then, use this quantity to calculate the mean square between (6 pts).If the F statistic calculated for these data is 8.49, what is the value of the mean square within n(4 pts)?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 (6 pts).Imagine you are interested in whether there is a significant difference between the mean age of marriage across educational groups.
