A medical study was interested in predicting the diastolic blood press from the systolic blood pressure. The following reading were obtained from 5 patients (Systolic, Diastolic): (134,87),(115,83),(113,77),(123,77),(119,69). Compute the correlation and least squares regression line. Select the TRUE statement below.
a. No answer is correct.
b. This regression line should not be used for prediction since the fit to the data is marginal.
c. Line: Systolic = a Diastolic +b, correlation: r
d. Diastolic =0.4 Systolic +30.0,r=0.93
e. For a 10 unit increase in Systolic pressure the line indicates there would be a 42 unit increase in Diastolic pressure.
