A study reported that in a sample of 81 men, 25 had elevated total cholesterol levels (more than 200 milligrams per deciliter). In a sample of 99 women, 34 had elevated cholesterol levels.
Can you conclude that the proportion of people with elevated cholesterol levels differs between men and women? Use the $\alpha = 0.05$ level of significance.

To conclude a difference in proportions, a statistical test such as a two-proportion z-test should be conducted. The problem does not provide the test result or p-value, so we cannot conclude based solely on the given data.

A Study Reported That in a Sample of 81 Men α=0.05\alpha = 0.05α=0.05
