The mayor is interested in finding a 90% confidence interval for the mean number of pounds of trash per person per week that is generated in the city. The study included 124 residents whose mean number of pounds of trash generated per person per week was 37.7 pounds and the standard deviation was 8.2 pounds. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a ?v distribution. b. With 90% confidence the population mean number of pounds per person per week is between and pounds. c. If many groups of 124 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 percent will not contain the true population mean number of per week and about pounds of trash generated per person per week.

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.20 ml/kg for the distribution of blood plasma.
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 city. The study included 160 residents whose mean number of pounds of trash generated per person per week was 36.7 pounds and the standard deviation was 7.7 pounds. 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 160 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.
The mayor is interested in finding a 90% confidence interval for the mean number of pounds of trash per person per week that is generated in the city. The study included 249 residents whose mean number of pounds of trash generated per person per week was 34.5 pounds and the standard deviation was 6.2 pounds. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a ? 0 distribution. b. With 90% confidence the population mean number of pounds per person per week is between and pounds. c. If many groups of 249 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 percent will population mean number of pounds of trash generated per person per week and about not contain the true population mean number of 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 185 residents whose mean number of pounds of trash generated per person per week was 37.2 pounds and the standard deviation was 6.3 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 185 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.

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.
