![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)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3b0be5ad-1d63-489c-97ab-6c65620cd926%2F8480c1a4-ab0c-4f9a-b166-71aa528716ef%2F74hlqra_processed.jpeg&w=3840&q=75)
