Answer to the question is as follows. Please write back in case of doubts:
1.
The MSE or Mean squared Error is the pooled standard deviation.
It is given by 6.32
The degree of freedom asked in the question is given by = totaldf from the ANOVA figure = 14
2. Similarly,
Pooled standard deviation = 41.54
The degree of freedom asked in the question is given by = totaldf from the ANOVA figure = 23
