Dr. Gupta conducts a study to examine whether eating cookies influences memory. She draws a sample of n = 36 participants. The population from which they were selected had a mean memory score of µ = 45 on a memory test. After eating cookies, the sample mean is found to be M = 58 and the estimated standard error is 0.74. Calculate the effect size in terms of the proportion of variance accounted for (r2). 0.93 0.73 0.23 0.55
