An experiment was performed on a certain metal to determine if the strength is a function of heating time.The sample size consists of ten metal sheets.The simple linear regression equation is = 1 + 1X.The time is in minutes and the strength is measured in pounds per square inch.One of the ten metal sheets was heated for 4 minutes and the resulting strength was 6 lbs.per square inch.Calculate the value of the residual for this observation.
A)2
B)1
C)-4
