please help meeeeee f

Here is an ANOVA summary table for a 2-way fixed-effects balanced design. Using =FINV ( ) in Excel, find the critical values for each hypothesis test at both the a = 0.05 and a = 0.01 significance levels. Source SS df MS F Fo.05, dfi , dfz Fo.01, dfi , dfa A 6866 4 1716.5 3.022 B 4476.7 2 2238.35 3.941 A x B 6819.7 8 852.463 1.501 Error 110760 195 568 TOTAL 128922.4 209 Round to four decimal points. Finally, what was the sample size for each cell in this 2-factor design? n = Hint: Add 1 to the total degrees of freedom to compute the overall total number of data values in the table. Next, add 1 to the of for A & B to compute the actual number of groups in each row category (A) & column category (B). Now to compute the sample size simply take the overall total (df+1) divided by the PRODUCT of the number of row and column groups. This will produce "n" or the number of samples in each grouping
