Ch 9, #10 (pg. 264) Stats Question: A random sample of n=4 individuals is selected from a population with mu = 35, and a treatment is administred to each individual in the sample. After treatment, the sample mean is found to be M = 40.1 with SS = 48. Based on the sample data, does the treatment have a significant effect? Use a two-tailed test with alpha = .05.
