Tedtment Group Control Group Average SAT score 1,242 1,210 Standard deviation of SAT score 93.2 97.1 Number of men 56 44 Number of women 44 56 Estimate the average treatment effect on test scores. Average treatment effect = 32 points. (Enter your response as an integer.) There would be nonrandom assignment if men (or women) had different probabilities of being assigned to the treatment group and to the control group. Let Men denote the probability that a male is assigned to the treatment group. Random assignment to a group means PMen = 0.5. Calculate the t-statistic for random assignment of a male to a group under the null hypothesis of Men = 0.5 at the 10% level of significance. t-statistic = . (Round your response to two decimal places.) Using this calculation, there evidence of nonrandom assignment
