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 find the P-value using a=0.02. Is there sufficient evidence to conclude that there is a linear correlation between systolic measurements and diastolic measurements?
systolic (x) 137 130 140 121 126 124 127 132 125 145 140 138
diastolic (y) 94 93 99 81 87 83 82 85 80 98 104 97
