An experiment was performed on a certain metal to determine if the strength is a function of heating time. The sample size consists of 10 metal sheets. The simple linear regression equation is ŷ = 1 + 1X. The time is in minutes and the strength is measured in pounds per square inch. One of the 10 metal sheets was heated for 4 minutes and the resulting strength was 6 lb per square inch. Calculate the value of the residual for this observation.
