Explanation / Answer
As per the Chegg policy, we are advised to do one question at a time so i am attempting the 3rd one.
3. Numerator degrees of freedom = k - 1 = 3 - 1 = 2
Denominator degrees of freedom = n - k = 10 - 3 = 7
Hence at 0.05 significance level,
Critical value = 4.41
Option C is correct.
