a. To compute the confidence interval use a ? distribution.
b. With 95% confidence the population mean commute for non-residential college students is
between
and
miles.
c. If many groups of 10 randomly selected non-residential college students are surveyed, then a
different confidence interval would be produced from each group. About
percent of
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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fade7408c-2f27-4f21-a314-48a4e9e58957%2F073c61b5-698e-4dcb-96e0-842de0a51b06%2Fk0drhu8_processed.jpeg&w=3840&q=75)
