The blood pressure measurements 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 the P-value using a=0.05 is there sufficient evidence to conclude that there is a linear correlation between systolic measurements and diastolic measurements?
