Do Ne your conclusionsuisticli

Answer 1

Ans:

3)False

4)

a)N=15

k=3

df(numerator)=3-1=2

df(denominator)=N-k=15-3=12

b)

Critical F value=FINV(0.05,2,12)=3.885

c)

As,F=3.44 is less than 3.885,we fail to reject null hypothesis.

d)

There is not sufficient evidence to conclude that there is difference among three means.
