pressure–automobile mileage data

Tire wear and pressure. Suppose you want to use the coding system for observational data to fit a second-order model to the tire pressure–automobile mileage data in Exercise 5.10 (p. 272), which are repeated in the table.

(a) Give the equation relating the coded variable u to pressure, x, using the coding system for observational data.

(b) Calculate the coded values, u.

(c) Calculate the coefficient of correlation r between the variables x and x2.

(d) Calculate the coefficient of correlation r between the variables u and u2. Compare this value to the value computed in part c.

(e) Fit the model

using available statistical software. Interpret the results.
