In order to study any possible relationship between age and change in systolic blood pressure (BP) (mm Hg) in 24 hours in response to a treatment, the following data were obtained from 11 individuals.

Age	70	51	65	70	48	70	45	48	35	48	30
Systolic BP change	-28	-10	-8	-15	-8	-10	-12	3	1	-5	5

(a) Draw a scatterplot.

(b) Find the sample correlation of age and systolic BP.

(c) Fit a least-squares regression line.

(d) Interpret (a), (b), and (c).
