Question
C6. You have been doing research for your statistics class on the prevalence of binge
drinking among teens.
a. According to 2011 Monitoring the Future data, the average binge drinking score, for this
sample of 914 teens, is 1.27, with a standard deviation of 0.80. Binge drinking is defined
as the number of times the teen drank five or more alcoholic drinks during the past week.
Construct the 95% confidence interval for the true average severe binge drinking score.
b. Your roommate is concerned about your confidence interval calculation, arguing that
severe binge drinking scores are not normally distributed, which in turn makes the
confidence interval calculation meaningless. Assume your roommate is correct about
the distribution of severe binge drinking scores. Does that imply that the calculation
of a confidence interval is not appropriate? Why or why not?
