Confidence in banks: A news poll conducted in 2012 asked a random sample of 1217 adults in the United States how much confidence they had in banks and other financial institutions.

8 A New York Times article reported that a survey conducted in 2014 included 36,000 adults, with 1,500 of them being regular users of e-cigarettes. Because e-cigarette use is relatively new, there is a need to obtain today's usage rate. How many adults must be surveyed now if we want a confidence level of 90% and a margin of error of 1.5 percentage points?
A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
