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 = 0.05. Is there sufficient evidence to conclude that there is a linear correlation between systolic measurements and diastolic measurements?

systolic (x) 137 131 141 121 125 121 127 130 132 143 141 139

diastolic (y) 91 91 99 85 88 83 82 86 82 98 106 95

What are the null and alternative hypothesis?

The linear correlation coefficient is ___

the test statistic t is ___

the P-value is ____

Because the P-value is (greater or less) than the significance level 0.05, there (is not or is) sufficient evidence to support the claim that there is a linear correlation between systolic measurements an=0.05d diastolic measurements for a sifnificance level of a
