Does exercise improve the human immune system? An experiment was conducted by a physiologist at the University
Question:
Does exercise improve the human immune system? An experiment was conducted by a physiologist at the University of Florida to determine whether such a relationship exists. Thirty subjects volunteered to participate in the study. The amount of immunoglobulin known as IgG (an indicator of long-term immunity) and the maximal oxygen uptake (a measure of aerobic fitness level) were recorded for each subject. The resulting data are given in the accompanying table.
a. Construct a scattergram for the IgG–maximal oxygen uptake data.
b. Hypothesize a probabilistic model relating IgG to maximal oxygen uptake.
c. Fit the model to the data and give the least-squares prediction equation.
d. Assess the adequacy of the model.
