Two people are arguing about the size of different breeds of dogs. One believes that German shepherds are larger than huskies, while the other person believes the opposite is true. They conduct a study to see which one of them is correct. They sample the weights of ten dogs of each breed. The data are as follows: German Shepherds: 55, 72, 61, 43, 59, 70, 67, 49, 55, 63 Huskies: 48, 77, 46, 51, 60, 44, 53, 61, 52, 41 (a) Should a one-tailed or two-tailed test be conducted? Why? (b) Conduct the appropriate test with alpha = 0.05. Which breed is larger or are they the same?
