Answer 1

Ho:$\mu1=\mu2=\mu3$​​​​​​

vs

H1:At least one of the three means are not equal.

​Where

Summary of Data Treatments Total 4 8 649 736 2069 Mean 81.125 92 85.5 86.208 52753 67754 58710 179217 2x2 3.8336 Std.Dev 6.0862 2.4495 5.7071 Result Details MS Between- treatments 479.0833 239.5417 F 13.49078 Within- treatments 372.875 17.756 21 Total 851.9583 23

F=MSbetween treatments /MSwithin treatments.

MS(X) =SS(X) /df(X)

f =13.49

p value=0.000171

As p value is less than alpha.We reject null hypothesis

Conclusion :

c is correct answer.
