Two Proportions: Videos & Practice Problems

Researchers studied the effect of a dietary supplement on cholesterol reduction. In the study, $90$ participants took the supplement and $90$ took a placebo. Of those who took the supplement, $27$ achieved a significant reduction in cholesterol, while $63$ did not. Of those who took the placebo, $9$ achieved a significant reduction, while $81$ did not. At the $0.05$ significance level, is there evidence to reject the claim that the proportion of participants achieving significant cholesterol reduction is the same for both groups?
