An article in the IEEE Transactions on Instrumentation and Measurement [Direct, Fast, and Accurate Measurement of VT and K of MOS Transistor Using VT-Sift Circuit (1991, Vol. 40, pp. 951955)] described the use of a simple linear regression model to express drain current y (in milliamperes) as a function of ground-to-source voltage x (in volts). The data are as follows:(a) Draw a scatter diagram of these data. Does a straight-line relationship seem plausible? (b) Fit a simple linear regression model to these data. (c) Test for significance of regression using 0.05. What is the P-value for this test? (d) Find a 95% confidence interval estimate on the slope. (e) Test the hypothesis H0: 0 0 versus H1: 0 0 using 0.05. What conclusions can you draw?
