The mayor is interested in finding a 9596 confidence interval for the mean number of pounds of trash per person per week that is generated in the citv. The stud}.r included 222 residents whose mean number of pounds of trash generated per person per week was 36.1 pounds and the standard deviation was 15.9 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 l and l pounds. c. If manyr groups of 222 randomlyr 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 gene-rated per person per week
