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 14 randomly selected non-residential college
students are surveyed, then a different confidence interval would be
produced from each group. About 98
confidence intervals will contain the true population mean number of
percent of these
missed class days and about 2
percent will not contain the true
population mean number of missed class days.
