What is your conclusion about this claim? A. At 2% level of significance, I have enough evidence to conclude that this treatment has no significant affect.B. Add 2% level of significance, I do not have enough evidence to conclude that this treatment has significant effect.C.

A sample is selected from a population with A = 150. After a treatment is administered to the individuals, the sample mean is found to be X = 140 and the standard deviation is S= 9. If the sample has n = 18 scores, determine whether the sample is sufficient to conclude that the treatment has significant effect. Use a two tail test with @ = 0.02. ( Assume the population is normally distributed)
