A group of scientists were interested in the relationship between heart rate and blood pressure after the intake of caff
A group of scientists were interested in the relationship between heart rate and blood pressure after the intake of caffeine in a group of 40 healthy males. Post-caffeine consumption, the mean systolic blood pressure measured was 129.1mmHg with SD of 5.67mmHg, and the mean heart rate was 78.1 beats per minute (bpm), with SD of 9.33 bpm. A least squares regression line was fitted to the data with the blood pressure as the response variable and the heart rate as the explanatory variable, and the y-intercept was found to be 105.56mmHg. Find the correlation coefficient representing this relationship. Round final answer to 3 decimal places. Do not round in intermediate steps.
