The blood pressure requirements of a single patient were taken by twelve different medical students and the results are listed below. Construct a scatterplot find the value of the linear correlation coefficient r, and find the P-value using a =0.05.Is there sufficient to conclude that there is alinear correlation between systolic measurements and diastolic measurements?
