A university dean wants to estimate the percentage of students at her university who drink alcohol of one kind or another. If she wants to estimate this percentage to within +1% with 80% confidence, how many students should she sample? . In a random sample of 1200 college students, 848 say they drink alcohol of one kind or another. Construct a 95% confidence interval for the percentage of college students who drink alcohol of one kind or another. Make sure to state and check all conditions and state your conclusion in context. . Use your confidence interval in part b to test if the percentage of college students who drink alcohol of one kind or another differs from the 61% figure for American adults. Make sure to state the hypotheses, but you do not need to check the conditions.

A psychologist wanted to know if students in her class were more likely to cheat if they were low achievers. She divided her 60 students into three groups (low, middle, and high) based on their mean exam score on the previous three tests. She then asked them to rate how likely they were to cheat on an exam if the opportunity presented itself with a very limited chance for consequences. The students rated their desire to cheat on a scale ranging from 1-100, with lower numbers indicating less desire to cheat.
