Question

A study examined the fat content (in grams) for samples of beef and meat hot dogs. The resulting 96% confidence interval for mu_Meat - mu_Beef is (- 5.2, - 2.1). Complete parts a) through c) below. a) The endpoints of this confidence interval are negative numbers. What does that indicate? The mean fat contents for each type of hot dog varies greatly from the other. The mean fat content is probably higher for beef hot dogs. The mean fat content is probably higher for meat hot dogs. The type of hot dog with a higher mean fat content cannot be determined. b) What does the fact that the confidence interval does not contain 0 indicate? The difference in the two sample means is insignificant. Both samples have a lot of variation. The difference in the two sample means is significant. There is no difference between the two samples. c) If we use this confidence interval to test the hypothesis that mu_Meat - mu_Beef = 0, what's the corresponding alpha level? %
