Calculate the best systolic blood pressure in the left arm, if the systolic blood pressure in the arm right is 100 mm Hg. Right arm 102 101 94 79 79 Left arm 175 169 182 146 144
Excel is used for the problem.
For the given dataset, first a scatter plot then a line is fitted in it.
Therefore the best fitted line is :
y = -0.158x2+29.89x-1225
y = Left Arm
x = Right Arm
The best systolic blood pressure in the left arm, if the systolic blood pressure in the right arm is 100 mm Hg is
y = -0.158*1002+29.89*100-1225 = 184
