A researcher wanted to investigate the linear relationship between serum cholesterol level and body mass index (BMI) of men in their fifties. He measured both variables from a random sample of 32 men and calculated a correlation of 0.74. The sample mean cholesterol was 185.21 mg/dl with a standard deviation of 19.47 mg/dl, and the sample mean BMI was 20.51 with a standard deviation of 3.21. He confirmed that all relevant assumptions were met. (***Practice: find b0 and b1 based on the context) Y = -2.086 + 0.122* Chol Work) What is the predicted BMI of a man with a serum cholesterol level of 173.21 mg/DL?Work) A researcher measured man with a serum cholesterol level of 173.21 mg/DL. His BMI was 23.04. Calculate the residual value for BMI. Did the model over predict or under predict? Type your residual calculate
