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 118 residents whose mean number of pounds of trash generated per person per week was 34.1 pounds and the standard deviation was 8.4 pounds. Round answers to 4 decimal places where possible.  If many groups of 118 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

 If many groups of 118 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.
