Question: A sample of n = 16 individuals is selected from a normal population with a mean of \(\mu \) = 48 and a standard deviation of \(\sigma \) = 12. After receiving a treatment, the sample mean is found to be M = 52.

a. If the sample mean were M = 56, what value would be obtained for Cohen’s d?

b. If the sample size were n = 36, what value would be obtained for Cohen’s d?

c. If the population standard deviation were \(\sigma \) = 24 what value would be obtained for Cohen’s d?
