Do male and female servers at Swank Bar work the same number of hours? A sample of 65 fenale servers worked an average of 35 hours per week, with a standard deviation of 4.2. A sample of 62 male servers worked an average of 37 hours per week, with a standard deviation of 3.9. Let µi and u2 represent the typical number of hours worked by all female and male servers at Swank Bar, respectively. Estimate with a 83% confidence level how many more hours female servers work. Round answers to three decimal places. Fcdf = Do we pool then? O Yes O No 83% Confidence Interval: Which of the following does your data suggest? O Female and male servers work about the same number of hours O Female servers work more hours Male servers work more hours
