A random sample of n=16 scores is obtained from a population with a mean of 80, and a treatment is administered to the sample. After treatment, the sample mean is found to be M=82.

a. Assuming the sample variance is 64, compute the estimated d and r2 (r squared) to measure the size of the treatment effect. (show all steps and formulas)

b. Assuming the sample variance is 1600, compute the estimated d and r2 (r squared) to measure the size of the treatment effect. (show all steps and formulas)
