Question

Transcribed Image Text:Do male and female servers at Swank Bar work the same number of hours? A sample of 65 female servers
worked an average of 30 hours per week, with a standard deviation of 2. A sample of 65 male servers
worked an average of 23 hours per week, with a standard deviation of 4.
Let 41 and uz represent the typical number of hours worked by all female and male servers at Swank Bar,
respectively. Estimate with a 90% confidence level how many more hours female servers work. Round
answers to the nearest hundredth.
Which of the following does your data suggest?
O Male servers work more hours
O Female servers work more hours
O Female and male servers work about the same number of hours
