Recall that the vendors' mean annual earnings. E(y), was modeled as a first-order function of age (x) and hours worked (x2). Now, consider the interaction model E(y)- Ao + 1Xi + 2x2 + 3XiX2. The SAS printout for the model is displaved in the next column (a) Give the least squares prediction equation (b) What is the estimated slope relating annual earnings (y) to age (x) when number of hours worked (x2) is 10? Interpret the result. (c) What is the estimated slope relating annual earnings (y) to hours worked (x2) when age (x) 1s 40? Interpret the result (d) Give the null hypothesis for testing whether age (x) and hours worked (x2) interact (e) Find the p-value of the test, part d (f) Refer to part e.
