Hello Sir/ Mam
YOUR REQUIRED ANSWER IS OPTION B : 0.516
We know that:
df for between groups is 1 less than the number of groups and total is 1 less than the total.
Hence, df for between is 3 while total is 23. Hence, for within is 20.
Also, sum of squares = mean squares*n
And
Coefficient of determination = SSG/ SST
Hence,
| Source | df | SS | MS |
| Treatment | 3 | 10368 | 3456 |
| Error | 20 | 9740 | 487 |
| Total | 23 | 20108 |
I hope this solves your doubt.
Feel free to comment if you still have any query or need something else. I'll help asap.
Do give a thumbs up if you find this helpful.

An experiment has a single factor with six groups and five values in each group. In determining the among-group variation, there are 5 degrees of freedom. In determining the within-group variation, there are 24 degrees of freedom. In determining the total variation, there are 29 degrees of freedom. Also, note that SSA = 120, SSW = 192, SST = 312, MSA = 24, MSW = 8, and FSTAT = 3. Complete parts (a) through (d). Click here to view page...
