You are interested in finding a 98% confidence interval for the
average number of days of class that college students miss each
year. The data below show the number of missed days for 10 randomly
selected college students. Round answers to 3 decimal places
where possible.
a. To compute the confidence interval use
a ? z t 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 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 missed class days and about percent will not
contain the true population mean number of missed class
days.
