You draw a random sample of 150 girls, and find that the mean number of delinquent acts is 3.35. You are testing the hypothesis that girls offend at a different rate than the general juvenile population using an alpha level of 0.05. You obtain a p-value of 0.0314 from Table A1. What conclusion do you reach?
