Answer #1

for above degree of freedom of numerator =k-1=3-1=2

degree of freedom for denominator =n1+n2+n3-k=8+10+7-3=22

for 0.05 level and (2,22) degree of freedom ; critical value =3.44

as test statistic 3.95 is higher then critical value ; we reject null hypothesis

option 2 is correct , Reject Ho
