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 189 residents whose mean number of pounds of trash generated per person per week was 35.4 pounds and the standard deviation was 8.3 pounds. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a ?v distribution. b. With 95% confidence the population mean number of pounds per person per week is between and pounds. c. If many groups of 189 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.

Question

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 189 residents whose mean number of
pounds of trash generated per person per week was 35.4 pounds and the standard deviation was 8.3
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 189 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.
