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 28 hours per week, with a standard
deviation of 4.
Let μ1μ1 and μ2 represent the typical number of hours worked by all
female and male servers at Swank Bar, respectively. Estimate with a
87% confidence level how many more hours female servers work. Round
answers to the nearest hundredth.
< μ1−μ2 <
Which of the following does your data suggest?
- Female and male servers work about the same number of hours
- Male servers work more hours
- Female servers work more hours

0.05. Suppose that 113 randomly selected male college students and
84 randomly selected female college students were asked about their
living arrangements: dormitory, apartment, or other. The results
are shown in Table. Do male and female college students have the

The number of hours that should be worked by a full-time bar
attendant is stipulated in the Queensland award as 36.25 hours per

attendants is not that specified in the award. From a random sample
of 38 workers, it was found that the average working week was 36.65
hours with a variance of 0.85 hours squared. On the basis...

In a survey of a sample of 200 guests (100 male and 100 female)
on a major cruise line A, it
was found that 45 male guests and 55 female quests were
satisfied. However, the cruise line advertised that 65% of its
guests (overall) were satisfied. Undertake a hypothesis test at a
5% significance level to examine if the claim made by the cruise
line can be supported with the data.
From the results of the survey in part b,...
