Use the following Pulse Rates, and Diastolic Blood Pressures:
\table[[Pulse Rate,86,72,82,82,64,68,70,78,96,72,60,98],[\table[[Diastolic Blood],[Pressure]],70,66,74,64,74,52,90,70,68,74,60,68]]
(i) Calculate the correlation coefficient between Pulse Rate and Diastolic Blood Pressure.
(ii) Obtain the best line of fit between Pulse Rate and Diastolic Blood Pressure with Diastolic Blood Pressure as the response variable.
(iii) Use the above best line of fit to predict Diastolic Blood Pressure based on a given Pulse Rate of 90 per minute.
(iv) Test if the slope for the line in part (ii) is different from 0 using 0.05 level of significance.
(v) Test if the correlation coefficient between Pulse Rate and Diastolic Blood Pressure is different from 0 using 0.05 level of significance.
