A study examined the fat content (in grams) for samples of beef and meat hot dogs. The resulting 98% confidence interval for HMeat - HBeef is (1.8,4.8). Complete parts a) through c) below. a) The endpoints of this confidence interval are positive numbers. What does that indicate? O A. The type of hot dog with a higher mean fat content cannot be determined. O B. The mean fat content is probably higher for meat hot dogs. OC. The mean fat contents for each type of hot dog varies greatly from the other. O D. The mean fat content is probably higher for beef hot dogs. b) What does the fact that the confidence interval does not contain 0 indicate? O A. There is no difference between the two samples. O B. The difference in the two sample means is insignificant. OC. Both samples have a lot of variation. O D. The difference in the two sample means is significant. c) If we use this confidence interval to test the hypothesis that uMeat - HReef = 0, what's the corresponding alpha level?
