The following sample data were obtained from different
second-year medical students who took blood pressure measurements
of the same person. Conduct a formal hypothesis test to test for a
linear correlation between the systolic and diastolic readings. Use
a 0.05 significance level.

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
alphaαequals=0.050.05.
Is there sufficient evidence to conclude that there is a linear
correlation between systolic measurements and diastolic
measurements?
