Given effect size and confidence interval, interpret the results. Be sure to

(1) Tell what was done,

(2) Present some facts,

(3) Interpret the results, and

(4) Make a suggestion for future research. (Assume the test is two-tailed and α = .05.)

Given the supplied information, interpret the results. A dean compared the GPA of a sample (N = 20) of students who spent more than two hours a night on homework (M = 3.20, s = 0.50) to the average GPA at her college (μ = 2.80). She was curious if homework had any relationship, either positive or negative, with GPA. She found:
• t_cv = 2.093
• t = 3.64
• d = 0.80
• 95% CI [0.17, 0.63]
