A high of 10 was possible A sample of five tests was selected from each group. The test grade results were: At the 0.01 level, what is the critical value? (Points 2) ? 1.00 3.24 1.96 ? 529

Answer 1

here degree of freedom for numerator =groups-1=4-1=3

degree of freedom for denminator =N-k=4*5-4=16

hence for (3,16 )df and 0.01 level ; critical value of F =5.29

18)

degree of freedom for treatments =number of treatments -1=3-1=2
