How to do an ANOVA TEST (Analysis Of Variance) with this data, specifically how to get the obtained f and critical f ? Null: muA=muB=muC   Alternative: muA≠muB≠muC n = 15 , The grand mean = 10 ,The group means are: 6.2 for A, 15.2 for B, and 8.6 for C This is a sideways tabele because the table provided only goes to 10 rows and I need 15.  i |  A,A,A,A,A,B,B,B,B,B,C,C,C,C,C x |  7,6,4,7,716,16,15,17,12,7,9,10,8,9  The main sum of squares is 244 (before splitting up to between or whatever.)
