Question
You are interested in finding a 98% confidence interval for the average commute that non-
residential students have to their college. The data below show the number of commute miles
for 11 randomly selected non-residential college students. Round answers to 3 decimal places
where possible.
21 19 24 21 24 7 28 27 7 10 18
a. To compute the confidence interval use a
distribution.
b. With 98% confidence the population mean commute for non-residential college students is
between 12.116 X and 25.338 X miles.
c. If many groups of 11 randomly selected non-residential college students are surveyed, then a
different confidence interval would be produced from each group. About 98
percent of
these confidence intervals will contain the true population mean number of commute miles and
about 2 percent will not contain the true population mean number of commute miles.
