I did some of the question. I was wondering if I am doing it right?

6. (36 pts) The following is an incomplete ANOVA summary table:

Source	df	SS	MS	F
Among Groups	3	63	63/3=21	21/6.06=3.47
Within Groups	16	97	97/16=6.06
Total	19	160

(a) Complete the ANOVA summary table.

(b) Determine the number of groups.

In F-table, df₁ = 3

We know that df₁ = k-1

Hence k= 4, which is the number of groups

(c) At the = 0.05 level of significance, determine whether there is evidence of difference in the population means.
