i just need help with (b)

A random sample of 24 adult male wolves from the Canadian Northwest Territories gave an average weight x, = 96.0 pounds with estimated sample standard deviation s, = 6.0 pounds, Another sample of 29 adult male wolves from Alaska gave an average weight x2 = 89.8 pounds with estimated sample standard deviation s, = 6.6 pounds. (a) Categorize the problem below according to parameter being estimated, proportion p, mean , difference of means /, - 2, or difference of proportions p, - P2. Then solve the problem. HI - H2 OP OPI - P2 (b) Let /, represent the population mean weight of adult male wolves from the Northwest Territories, and let /2 represent the population mean weight of adult male wolves from Alaska. Find a 95% confidence Interval for , - utz. (Use 1 decimal place.) lower limit 0.2 X X upper limit 11.9 (C) Examine the confidence Interval and explain what it means in the context of this problem. Does the Interval consist of numbers that are all positive? all negative? of different signs? At the 95% level of confidence, does it appear that the average weight of adult male wolves from the Northwest Territories is greater than that of the Alaska wolves? Because the Interval contains only positive numbers, we can say that Canadian wolves weigh more than Alaskan wolves, Because the interval contains both positive and negative numbers, we can not say that Canadian wolves weigh more than Alaskan wolves. O We can not make any conclusions using this confidence Interval, O Because the interval contains only negative numbers, we can say that Alaskan wolves weigh more than Canadian wolves
