CI in part 1 was 1.7 and 2.9

Dogsled drivers, known as mushers, use several different breeds of dogs to pull their sleds. One proponent of Siberian Huskies believes that sleds pulled by Siberian Huskies are faster than sleds pulled by other breeds. He times 34 teams of Siberian Huskies on a particular short course, and they have a mean time of 7.6 minutes. The mean time on the same course for 50 teams of other breeds of sled dogs is 5.3 minutes. Assume that the times on this course have a population standard deviation of 1.1 minutes for teams of Siberian Huskies and 1.6 minutes for teams of other breeds of sled dogs. Let Population 1 be sleds pulled by Siberian Huskies and let Population 2 be sleds pulled by other breeds. Step 2 of 2: Interpret the confidence interval obtained in Step 1. Answer 2 Points Tables Keypad Keyboard Shortcuts Since the confidence interval does not contain zero, the data do not provide evidence that the population means are unequal at a 95 % confidence level. Since the confidence interval contains zero, the data do not provide evidence that the population means are unequal at a 95% confidence level. We are 95% confident that the mean time on this course for sleds pulled by Siberian Huskies is between 1.7 minutes and 2.9 minutes faster than Next the mean time on this course for sleds pulled by other breeds of sled dogs. We are 95% confident that the mean time on this course for sleds pulled by Siberian Huskies is between 1.7 minutes and 2.9 minutes slower than the mean time on this course for sleds pulled by other breeds of sled dogs
