From a university population,random samples of 145 men and 237 women have been asked if they have ever cheated in a college class.8% of the men and 6% of the women said that they have.What is the appropriate test to assess the significance of this difference?
A)test for the significance of the difference between two sample proportions,large samples
B)test for the significance of the difference between two sample proportions,small samples
C)test for the significance of the difference between two sample proportions,matched samples
D)test for the significance of the difference between two sample means,large samples

The appropriate test to assess the significance of this difference is a test for the significance of the difference between two sample proportions, using large samples. This is because the sample sizes are sufficiently large (n>30) for both men and women, and we are comparing the proportions of two independent samples (men vs women) with a binary outcome (cheating or not cheating). Therefore, the appropriate test would be a two-sample z-test for the difference in proportions.
