Suppose we complete a case-control study that yields a study OR = 0.50. If we were told the true OR in the population was actually 0.25 (we normally wouldn’t know this, but suppose hypothetically someone was able to know this and told us), this means our study OR is biased. Is our study OR biased towards or away from the null? A)Towards the null. B)Away from the null.

According to the most recent General Social Survey, 70% of adults watch TV nightly. A researcher believes that the proportion of college students who watch TV nightly is less than this. To test this claim the research samples 400 college students and finds that 276 watch TV nightly. At the 0.05 level of significance does this data provide evidence to suggest that the proportion of college students who watch TV nightly is less than 70%?
