Here is a simple linear regression modell 15' = XS + L. We then get this from a sample ' _ 21 167 . _ 153.49 _ _ XX _ l 16? 154? ) X E -( Imam ). SSRes _ 43.581\" Use this information to answer the following: 1] Using the given information what is the predicted line? 2] What is the 95% condence interval for d' ? 3] when the explanatory variables equal 0, calculate the 90% prediction interval of Y. 4] Compare to the answer from question [3], if the condence interval for mean response is 90% when the explanatory variable equals 0, will it be wider or narrower than question [3]? You do not need to show calculations just explain
