Transcribed Image Text: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 t
distribution.
b. With 98% confidence the population mean commute for non-residential college students is
between
and
miles.
percent of
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
these confidence intervals will contain the true population mean number of commute miles and
about
percent will not contain the true population mean number of commute miles.
