In a random sample of 50 college students, 39 say they drink alcohol of one kind or another. The dean of students wants to study whether a higher percentage of college students drink alcohol than in the adult population at large and calculates a 95% confidence interval to be .640 to .885. How would the width of this confidence interval change (if at all) if instead of looking at the proportion of the sample who drinks alcohol of one kind or another, the dean focused on the proportion of the sample who do not drink alcohol of any kind at all? Group of answer choicesa. The new confidence interval would be narrower (have a smaller range) than the original confidence interval.
b. There is not enough information to tell.
c. The new confidence interval would be wider (have a larger range) than the original confidence interval
d. The new confidence interval would be the same width (have the same range) as the original confidence interval.
