Sampling for Differences in Sample Proportions Practice Test

A university compares the proportion of students who report being satisfied with dining services between on-campus and off-campus students. An SRS of $n_1=90$ on-campus students and an independent SRS of $n_2=110$ off-campus students are surveyed; $\hat p_1$ and $\hat p_2$ are the sample proportions satisfied. The sampling distribution of $\hat p_1-\hat p_2$ is modeled for repeated sampling. Which statement is correct?

A tech company compares the proportion of users who click a new button design on two versions of an app. Version A is shown to an independent random sample of $n_1=250$ users and Version B to $n_2=250$ users; $\hat p_1$ and $\hat p_2$ are the sample click proportions. The company considers the sampling distribution of $\hat p_1-\hat p_2$ over many repetitions. Which statement is correct?
