For the prostate data, fit a model with Ipas as the response and the other variables as predictors. Suppose a new patient with the following values arrives: Cavil = 1.44692 I weight = 3.62301 age = 65 lbph = 0.30010 svi = 0.000 lep = -0.79851 Gleason = 7.000 pggA.o - 15.000 Predict Ipas for this patient along with an appropriate 95% prediction interval. Repeat the last question for a patient with the same values except that his is age 20. For the model of the previous question, remove all the predictors that are not significant at the 5% level. Now compute the predictions of the previous questions. Are the intervals wider or narrower? Which prediction would prefer? Explain
