Dogs and fat The Consumer Reports article describedin Exercise 1 also listed the fat content (in grams) forsamples of beef and meat hot dogs. The resulting 90%confidence interval for mMeat - mBeef is (-6.5, -1.4).a) The endpoints of this confidence interval are negativenumbers. What does that indicate?b) What does the fact that the confidence interval doesnot contain 0 indicate?c) If we use this confidence interval to test the hypothesis that mMeat - mBeef = 0, what’s the corresponding al-pha level?
