The file sapphire lists observed values of Youngs modulus
Chapter , Problem 38(choose chapter or problem)
The file sapphire lists observed values of Young's modulus (g) measured at various temperatures (T) for sapphire rods (Ku 1969). Fit a linear relationship \(g=\beta_0+\beta_1 t\), and form confidence intervals for the coefficients. Examine the residuals.
