Sample of n=32 individuals is selected from a population that forms a normal distribution with mean μ=52. A treatment is administered to the sample and, after treatment, the sample is measured to evaluate the effect of the treatment. Be sure to show all formulas with symbols (and plug in numbers), steps, processes and calculations for all parts of the answers below.

a. Assuming that the population standard deviation is σ=7, compute Cohen's d to measure the effect size for a sample mean of M=42

b. Assuming that standard deviation, σ=3, compute Cohen's d to measure the effect size for a sample mean of M=42

c. Assuming that standard deviation, σ=9, compute Cohen's d to measure the effect size for a sample mean of M=48

d. Assuming that σ=4, compute Cohen's d to measure the effect size for a sample mean of M=48
