Question

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 o 0.05. ls there sufficient evidence to conclude that there is a linear correlation between systolic measurements and diastolic measurements? systolic (K 137 130 140 121 123 124 128 131 135 145 142 137 diastolic (y) What are the null and alternative hypotheses? O A. Ho: p 0 CO B. Ho: p a 0 H1: p> 0 O c. Ho: p 0 O D. Ho: p 0 H1: p

Explanation / Answer

Null and alternative hypothesis –Option-B

Scatter plot is option-D

Linear correlation is r=0.701

Test statistic t=r*sqrt(n-2)/sqrt(1-r2)=3.108

P-value=tdist(3.108,n-2,2)=tdist(3.108,10,2)=0.011

Last answers are “Less “ and “is”
