How would you figure these two problems out?

A random sample of 25 adult male wolves from the Canadian Northwest Territories gave an average weight x, = 97.8 pounds with estimated sample standard deviation s, = 6.3 pounds.
Another sample of 29 adult male wolves from Alaska gave an average weight x, = 89.8 pounds with estimated sample standard deviation s, = 6.7 pounds.
(a) Categorize the problem below according to parameter being estimated, proportion p, mean u, difference of means H1 - H2, or difference of proportions p1 - P2. Then solve the
problem.
O H1 - 42
p
O P1 - P2
(b) Let u, represent the population mean weight of adult male wolves from the Northwest Territories, and let u, represent the population mean weight of adult male wolves from
Alaska. Find a 95% confidence interval for u1 - H2. (Use 1 decimal place.)

Two-Sample T-Test for the population mean:

It is the hypothesis testing done for determining the mean difference between two sets of observations. As the name says it is paired t-test, the data of both samples are considered for the complete hypothesis testing and the test statistics will be found from those data.
