linear regression where am i going wrong??
Linear regression using least square fit method for the
determination of cocaine sample
Cocaine (mg/ml) Peak height
X= 2.75 Y=27377 X squared=0.9625 X x Y=3241.272
M = 10 x 3241.272 – 2.75 x 27377 / 10 x 0.9625 – 7.5625
= -42874.03 / 2.0625 = -20787.39 ?
I should be getting m = 267.25 according to graph
Can anyone tell me where I am going wrong please
