Explanation / Answer

Solution

a)

H0: µA = µB = µC Vs H1: At least one µ is different from the other µ’s.

b)

p-value (from output print-out) = 0.0009 which is much less than the level of significance,

? = 0.05 (also from output print-out). So, the null hypothesis, H0 is rejected.

Conclusion:

There is not sufficient evidence to suggest that the three groups have identical effect on the response variable.

c)

Mean effect of Group A and B are not significantly different. But, on an average Group C has a different effect on the response variable.
