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
= 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 a = 0.02. (Assume the population is normally distributed)
