Explanation / Answer
Ans:
a)H0:Mean ratings for three formulas are same.
b)H1: Mean ratings for three formulas are not same.
c)critical F value=FINV(0.05,2,9)=4.256
p-value=FDIST(29.089,2,9)=0.000118
As,p-value<0.05,we reject null hypothesis.
or
F=29.089>Fcritical=4.256,Reject null hypothesis.
We have suffcient evidence to conclude that Mean ratings for three formulas are not same.
