The blood pressure measurements of a single patient were taken by twelve different medical students and the results are listed below.
A Find the value of the linear correlation coefficient r
r=_____round to three decimal places
B Find the critical values of r from the table showing the critical values for the Pearson correlation coefficient using a = 0.05.
The critical values are +-_____round to three decimal places
Is there sufficient evidence to conclude that there is a linear correlation between systolic measurements and diastolic measurements? Why?
