Please use the following information to answer question 8a & 8b: A random sample of n = 16 scores is obtained from a population with a mean of µ = 45. After a treatment is administered to the individuals in the sample, the sample mean is found to be x̅ = 49.2. 8a. Assuming that the sample standard deviation is s = 8, calculate r2 (MUST SHOW WORK FOR THIS PROBLEM). Note: You must provide calculations for the t-observed statistic, in addition to r2. 8b. Calculate Cohen's d to measure the size of the treatment effect (MUST SHOW WORK FOR THIS PROBLEM).
