Each person in random samples of 227 male and 283 female working adults living in a certain town in Canada was asked how long, in minutes, his or her typical daily commute was. (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.)

Is there enough evidence to show that there is a difference in mean
commute times for male and female working residents of this town?
Use a significance level of 0.05.

Each person in random samples of 250 male and 250 female working
American adults was asked how long, in minutes, they typically
spend on their lunch break. The males averaged 39.6 minutes with a
standard deviation of 24.3 minutes. The females averaged 37.3
minutes with a standard deviation of 24.0 minutes. Is there
convincing evidence that the mean lunch break times for male and
female working American adults differ?

Random samples of female and male UVA undergraduates are asked
to estimate the number of alcoholic drinks that each consumes on a
typical weekend. The data is below:
Females (Population 1): 4, 5, 3, 6, 6, 4, 5, 3, 4, 2
Males (Population 2): 4, 6, 8, 4, 5, 6, 7, 6, 6, 7
Give a 95% confidence interval for the difference between mean
female and male drink consumption. For each confidence interval,
enter your answer in the form (LCL,...

Each person in a random sample of 228 male teenagers and a
random sample of 305 female teenagers was asked how many hours he
or she spent online in a typical week. The sample mean and standard
deviation were 15.2 hours and 11.3 hours for males and 14.2 and
11.7 for females. (Use a statistical computer package to calculate

Researchers equipped random samples of 46 male and 58 female
students from a large university with a small device that secretly
records sound for a random 30 seconds during each 12.5-minute
period over two days. Then they counted the number of words spoken
by each subject during each recording period and, from this,
estimated how many words per day each subject speaks. The female
estimates had a mean of 16,177 words per day with a standard
deviation of 7520 words...
