Problem 16SE

During the production of boiler plate, test pieces are subjected to a load, and their elongations are measured. In one particular experiment, five tests will be made, at loads (in MPa) of 11, 37, 54, 70, and 93. The least-squares line will be computed to predict elongation from load. Confidence intervals for the mean elongation will be computed for several different loads. Which of the following intervals will be the widest? Which will be the narrowest?

i. The 95% confidence interval for the mean elongation under a load of 53 MPa.

ii. The 95% confidence interval for the mean elongation under a load of 72 MPa.

iii. The 95% confidence interval for the mean elongation under a load of 35 MPa.
