It is believed that a certain drug can reduce a patient's pulse rate. In an experiment it was found that the larger the dose of the drug, the more the pulse rate reduced. A doctor wishes to find a regression equation which could be used to predict the pulse rate achieved for specific dosages. An experiment is carried out on four healthy individuals, varying the dose, x (in g), and measuring the corresponding pulse rate, y (in beats per minute). The table below shows values of x and y measured on 4 students. Individual A B C D Dose Xi 2.1 2.6 3.2 3.5 Pulse rate Yi 73 78 63 57 (a) Find the equation which represents the regression of y on x. y=x+ (Round to 2 decimal places. Round all intermediate values to 2 decimal places as needed.) C... It is believed that a certain drug can reduce a patient's pulse rate.
