10. A random sample is selected from a normal popula- tion with a mean of u 40 and a standard deviation of o 6. After a treatment is administered to the %3D individuals in the sample, the sample mean is found to be M 37. a. If the sample consists of n 36 scores, is the sample mean sufficient to conclude that the treat- ment has a significant effect? Use a two-tailed test with a = %3D b. If the sample consists of n-9 scores, is the sample mean sufficient to conclude that the treatment has a significant effect? Use a two-tailed test with
