Do female college students spend more time than male college
students watching TV? This was one of the questions investigated by
the authors of an article. Each student in a random sample of 46
male students at a university in England and each student in a
random sample of 38 female students from the same university kept a
diary of how he or she spent time over a three-week period.
For the sample of males, the mean time spent watching TV per day
was 68.6 minutes and the standard deviation was 67.5 minutes. For
the sample of females, the mean time spent watching TV per day was
93.8 minutes and the standard deviation was 89.1 minutes. Is there
convincing evidence that the mean time female students at this
university spend watching TV is greater than the mean time for male
students? Test the appropriate hypotheses using
α = 0.05.
(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 number, and your P-value to three decimal places.)

Fail to reject H0. We do not have convincing
evidence that the mean time female students at this university
spend watching TV is greater than the mean time for male
students.
Reject H0. We do not have convincing evidence
that the mean time female students at this university spend
watching TV is greater than the mean time for male
students.
Reject H0. We have convincing evidence that the
mean time female students at this university spend watching TV is
greater than the mean time for male students.
Fail to reject H0. We have convincing evidence
that the mean time female students at this university spend
watching TV is greater than the mean time for male students.

Reconsider Dr. Sameer's research question about how much time Cal Poly students spend on watching television. Suppose that for the random sample of 100 Cal Poly students the mean number of hours per day spent watching TV turns out to be 3.01 hours, and the standard deviation of the number of hours per day spent watching TV turns out to be 1.97 hours. Is the number 1.97 a parameter or a statistic? Assign an appropriate symbol to this number. Find...

A report states that the mean yearly salary offer for students graduating with a degree in accounting is $48,752. Suppose that a random sample of 50 accounting graduates at a large university who received job offers resulted in a mean offer of $49,890 and a standard deviation of $3300. Do the sample data provide strong support for the claim that the mean salary offer for accounting graduates of this university is higher than the national average of $48,752? Test the...

A researcher is interested in determining whether there is a difference in male college students and female college students' preference for taking online classes over on-campus classes. The researcher surveys 82 female students, and found that 15 preferred online classes. The researcher surveys 70 male students, and found that 10 preferred online classes. Let's perform a hypothesis test at the 5% significance level. Test whether the proportion of females who prefer online classes is greater than the proportion of males...
