Pra Chapter 8 Confidence Intervals (Mean) • Question 1 The mayor is interested in finding a 98% confidence interval for the mean number of pounds of trash per person per week that is generated in the city. The study included 152 residents whose mean number of pounds of trash generated per person per week was 32.4 pounds and the standard deviation was 7.8 pounds. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a ? O distribution. b. With 98% confidence the population mean number of pounds per person per week is between and pounds. c. If many groups of 152 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 1
The mayor is interested in finding a 98% confidence interval for the mean number of pounds of
trash per person per week that is generated in the city. The study included 152 residents whose
mean number of pounds of trash generated per person per week was 32.4 pounds and the
standard deviation was 7.8 pounds. Round answers to 3 decimal places where possible.
a. To compute the confidence interval use a
distribution.
?
b. With 98% confidence the population mean number of pounds per person per week is between
and
pounds.
c. If many groups of 152 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.
