A sample is selected from a population with μ = 46, and a treatment is administered to the sample. After treatment, the sample mean is M = 48 with a population standard deviation  = 4. Based on this information, what is the value of estimated Cohen’s d? a.           d = 0.125 b.           d = 0.25 c.           d = 0.50 d.           Cohen’s d cannot be computed without knowing the sample size.
