Aprofessor believes the students in a statistics class this term are more creative than most other students attending the university. a previous study found that students at the university had a mean score of 35 on a standard creativity test, and the current class has an average score of 40 on this scale with an estimated population standard deviation of 7. the standard deviation of the distribution of means is 1.63. what is the effect size?
a. (40 – 35) / 7 = 0.71
b. (40 – 35) / 1.63 = 3.07
c. (40 – 35) / 7² = 5 / 49 = 0.10
d. (40 – 35) / 1.63² = 5 / 2.66 = 1.88
