Question

Do male and female servers at Swank Bar work the same number of
hours? A sample of 45 female servers worked an average of 28 hours
per week, with a standard deviation of 2. A sample of 45 male
servers worked an average of 26 hours per week, with a standard
deviation of 3.

Let μ1and μ2 represent the typical number of hours worked by all
female and male servers at Swank Bar, respectively. Estimate with a
86% 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
- Female servers work more hours
- Male servers work more hours

Answer #1

Do male and female servers work the same number of hours? A
sample of 19 female servers worked an average of 36 hours per week,
with a standard deviation of 2. A sample of 27 male servers worked
an average of 40 hours per week, with a standard deviation of 5.
Let μ1 and μ2 represent the typical number of hours worked by all
female and male servers, respectively. Construct a 99% confidence
interval for μ1−μ2, assuming normal populations with...

Each person in a random sample of 226 male teenagers and a
random sample of 303 female teenagers was asked how many hours he
or she spent online in a typical week. The sample mean and standard
deviation were 15.1 hours and 11.3 hours for males and 14.1 and
11.8 for females. (Use a statistical computer package to calculate
the P-value. Use μmales − μfemales. Round your test statistic to
two decimal places, your df down to the nearest whole...

I'm interested in if women drink more pop than men. I randomly
asked the same about of men and women and came up with these sample
statistics:
Female Male
Sample Mean, x 4 5
Sample Standard deviation, s 3 2
Sample Size,n 20 20
My Hypotheses would be:
H0 : μ1 ≥ μ2
HA : μ1 < μ2
µ1 is Femle and µ2 is male.

An article reports that in a sample of 413 male college
students, the average number of energy drinks consumed per month
was 2.50 with a standard deviation of 4.87, and in a sample of 382
female college students, the average was 1.22 with a standard
deviation of 3.25. Can you conclude that the mean number of energy
drinks is greater for male students than for female students? Find
the P-value

A sociologist studied gender differences in the average number
of hours worked per day among employees at a law firm (there are 42
men and 19 women employed at this firm). She obtained the following
results: men work, on average, 52 hour per week and women work, on
average, 56 hour per week. The standard deviation for men is 12
hours and the standard deviation for women is 9 hours. Test the
null hypothesis of no difference in the average...

The 2006 General Social Survey contains information on the
number of hours worked by a respondent each week. The mean number
of hours worked per week is 39.04, with a standard deviation of
11.51. The sample size is 83.
c. Say we increased the sample size to 10,000 and found the same
mean and standard deviation. What would be the standard error?
d.If we increased the sample size to 10,000 what would be the
95% confidence interval for the mean...

In 2003, the
Accreditation Council for Graduate Medical Education (ACGME)
implemented new rules limiting work hours for all residents. A key
component of these rules is that residents should work no more than
80 hours per week. The following is the number of weekly hours
worked in 2017 by a sample of residents at the Tidelands Medical
