We can be 80% confident that the true proportion of college students with hypertension during finals week is ____ with a margin of error of ____.

Unless our sample is among the most unusual 10% of samples, the true proportion of college students with hypertension during finals week is between ___ and ____.

The probability, at 60% confidence, that a given college donor will have hypertension during finals week is ____, with a margin of error of _____.

Assuming our sample of donors is among the most typical half of such samples, the true proportion of college students with hypertension during finals week is between _____ and _____.

We are 99% confident that the true proportion of college students with hypertension during finals week is _____, with a margin of error of ____.

Assuming our sample of donors is among the most typical 99.9% of such samples, the true proportion of college students with hypertension during finals week is between _____ and ____.

Covering the worst-case scenario, how many donors must we examine in order to be 95% confident that we have the margin of error as small as 0.01? _____
