Question

The blood pressure measurement 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 measurement and diastolic measurements?;Systolic (x) 135, 132,140,121, 125, 124, 128, 130,131,143,141,138;Diastolic (y) 98, 92, 101, 85, 90, 81, 83, 83, 83, 96, 106, 95;What are the null and alternative hypothesis?;Construct a scatterplot, make a graph;The linear correlation coefficient r is? (round to three decimal places as needed);The test statistic t is? (round to three decimal places as needed);Because the P- value is (less or greater)? than the significance level 0.05 there (is or is not)? sufficient evidence to support the claim that there is a linear correlation between systolic measurement and diastolic measurement for a significance level of a=0.05
