a sample is selected from a population with u=50. after a treatment is administered to the individuals in the sample, the mean is found to be M=55 and the variance is s^{2 .}

equal 64. If the sample has n=4 scores , then conduct a hypothesis test to evaluate the significance of the treatment effect and calculate Cohen's d to measure the size of the treatment effect. Use a two-tailed test with alpha = .05

If the sample has n=16 scores, then conduct a hypothesis test to evaluate he significance of the treatment effect and calculate Cohen's d to measure the size of the treatment effect. Use a two-tailed test with alpha = .05
