The mayor is interested in finding a 99% confidence interval for the mean number of pounds of trash per person per week that is generated in the city. The study included 236 residents whose mean number of pounds of trash generated per person per week was 33.6 pounds and the standard deviation was 8.7 pounds. Round answers to 3 decimal places where possible.

b. With 99% confidence the population mean number of pounds per person per week is between
?
and
?  pounds.

c. If many groups of 236 randomly selected members are studied, 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 pounds of trash generated per person per week and about
?
percent will not contain the true population mean number of pounds of trash generated per person per week.
