To compare the average amount of time that Canadians and Americans spend commuting, a researcher collects a sample of 50 Canadians and 60 Americans. The Canadians spend an average of 4.6 hours a week commuting, with standard deviation 2,9 hours. The mean and standard deviation for the sample of Americans is 5.2 hours and 1.3 hours, respectively. The standard error of the difference of sample means is a) 2.314 b) 1.023 c) 0.443 d) 0.196 e) Cannot be computed as the sample sizes are different. 34.
