- Transistor gain is an integrated circuit device between emitter and collector (hFE) is related to twovariables, that can be controlled at the deposition process, emitter drive-in time (x1, in minutes), andemitter dose (x2, in ions x 1014). Fourteen samples were observed following deposition. The table shows the data. Determine if emitter dose influences gain in a linear relationship. Which regressor variable is thebest predictor of gain?Estimate f(2.1, 3.8) given that f(2, 4) = 6, fx(2, 4) = 0.9, and f,(2, 4) = -0.2.Find V(Y)
