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
