The mayor is interested in finding a 95% confidence interval for the mean number of pounds of trash per person per week that is generated in the city. The study included 222 residents whose mean number of pounds of trash generated per person per week was 36.9 pounds and the standard deviation was 8.9 pounds. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a distribution. b. With 95% confidence the population mean number of pounds per person per week is between and pounds. C. If many groups of 222 randomly selected members are studied, then a different confidence interval would be produced from each group. About 95 V percent of these confidence intervals will contain the true population mean number of pounds of trash generated per person percent will not containthe true population mean number of per week and about pounds of trash generated per person per week.

The mayor is interested in finding a 95% confidence interval for the mean number of pounds of
trash per person per week that is generated in the city. The study included 222 residents whose
mean number of pounds of trash generated per person per week was 36.9 pounds and the
standard deviation was 8.9 pounds. Round answers to 3 decimal places where possible.
a. To compute the confidence interval use a
distribution.
b. With 95% confidence the population mean number of pounds per person per week is between
and
pounds.
C. If many groups of 222 randomly selected members are studied, then a different confidence
interval would be produced from each group. About 95
percent of these confidence
intervals will contain the true population mean number of pounds of trash generated per person
percent will not contain the true population mean number of
per week and about
pounds of trash generated per person per week.
