A treatment is administered to a sample of n = 9 individuals selected from a population with a mean of LaTeX: \muμ = 80 and a st

andard deviation of LaTeX: \sigmaσ = 12. After treatment, the effect size is measured by computing Cohen’s d, and a value of d = 0.50 is obtained. Based on this information, what is the mean for the treated sample? Group of answer choices

Answer:

none of the above

Step-by-step explanation:

cohen's d= (Mean of population - mean of sample)/ standard deviation of population

0.5 = (80-mean of sample)/12

Mean of sample= 74
