For n-2=13degrees of freedom,P=0.3725 There is no sufficient evidence to support the existence of linear correlation between pulse rate and blood pressure. Using the correlation coefficient analysis, rweighpressure =0.453, rheighvpressure=0.253, rpulsepressure =0.092. Weight appears to be the best regressor. 4. The relationship between the braking distance s[m] and the speed v[km/h] of a car is given in the following table
