Assignment:
Body Temperature The table on the top of the next page lists the body temperatures (in oF) of subjects measured at 8:00 AM and later at midnight (based on Data Set in Appendix).

a. Construct a scatterplot. What does the scatterplot suggest about a linear correlation between 8:00 AM body temperatures and midnight body temperatures?
b. Find the value of the linear correlation coefficient and determine whether there is sufficient evidence to support a claim of a linear correlation between body temperatures measured at 8:00 AM and again at midnight.
c. Letting y represent the midnight temperatures and letting x represent the 8:00 AM temperatures, find the regression equation.
d. Based on the given sample data, what is the best predicted midnight body temperature of someone with a body temperature of 98.3°F measured at 8:00 AM?
