a. To compute the confidence interval use a ?
distribution.
b. With 98% confidence the population mean number of days of class that college students miss
is between
and
days.
c. If many groups of 11 randomly selected non-residential college students are surveyed, then a
percent of
different confidence interval would be produced from each group. About
these confidence intervals will contain the true population mean number of missed class days
and about
percent will not contain the true population mean number of missed class
days.
