A study examined the fat content (in grams) for samples of beef and meat hot dogs. The resulting 94% confidence interval for mu_Beef - mu_Meat is (- 4.8, - 1.1). Complete parts a) through c) below. a) The endpoints of this confidence interval are negative numbers. What does that indicate? A. The type of hot dog with a higher mean fat content cannot be determined. B. The mean fat content is probably higher for beef hot dogs. C. The mean fat contents for each type of hot dog varies greatly from the other. D. The mean fat content is probably higher for meat hot dogs. b) What does the fact that the confidence interval does not contain 0 indicate? A. Both samples have a lot of variation. B. There is no difference between the two samples. C. The difference in the two sample means is insignificant. D. The difference in the two sample means is significant. c) If we use this confidence interval to test the hypothesis that mu_Beef - mu_Meat = 0, what's the corresponding alpha level? %
