    A public health researcher suspected that there would be a relationship between the proportion of people in a state that engage in binge alcohol use and the proportion of people in the state that smoke cigarettes.  A regression analysis was performed and the output is shown below.  What is the correlation coefficient for percent cigarette smokers and percent binge drinkers?
    • A. 

      0.1887

    • B. 

      0.0356

    • C. 

      0.0160

    A study looked at medical records of about 25,000 patients, mostly in Asia.  They found that patients who drank at least three cups of green tea per day had a much lower incidence of depression.  In an American news article about this study, which of the following statements should not be made?
    • A. 

      It is possible that people who drink green tea also tend to have healthier lifestyles than those who don't.

    • B. 

      It is possible that people who drink green tea also tend to have a more positive outlook on life than those who don't.

    • C. 

      Because this is observational data, the association between drinking green tea and a lower incidence of depression is not an indication of a causal relationship.

    • D. 

      People who want to avoid depression should consider drinking green tea on a daily basis.

    • E. 

      Because most of these people lived in Asia, where tea drinking is much more common than in the United States, a similar association may not exist in the United States.

    Claire and Marc each created a simulated sampling distribution for a confidence interval. Claire simulated a CI for a mean with a known standard deviation, while Marc simulated a CI for a mean with an unknown standard deviation.  Which statement makes a correct comparison of their simulated sampling distributions?
    • A. 

      Both simulated sampling distributions are approximately normal.

    • B. 

      Claire's simulated sampling distribution is skewed to the right, and Marc's is roughly symmetric.

    • C. 

      Claire's simulated sampling distribution is approximately normal, and Marc's is approximately a t-distribution. Marc's sampling distribution has more variability.

    • D. 

      Claire's simulated sampling distribution is approximately a t-distribution, and Marc's is approximately normal. Claire's sampling distribution has more variability.

    • E. 

      Claire's simulated sampling distribution is approximately normal, and Marc's is approximately a t-distribution. Claire's sampling distribution has more variability.
