Answer: An engineer at a semiconductor company wants to
Chapter 12, Problem 12.16(choose chapter or problem)
An engineer at a semiconductor company wants to model the relationship between the gain or hFE of a device (y) and three parameters: emitter-RS (\(x_1\)), base-RS (\(x_2\)), and emitter-to-base-RS (\(x_3\)). The data are shown below:
(Data from Myers, Montgomery, and Anderson-Cook, 2009.)
(a) Fit a multiple linear regression to the data.
(b) Predict hFE when \(x_1 = 14\), \(x_2 = 220\), and \(x_3 = 5\).
