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. 951–955) 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: y 0.734 0.886 1.04 1.19 1.35 1.50 1.66 1.81 1.97 2.12 x 1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9 2.0 round your answers to 3 decimal places. (a) fit a simple linear regression model to these data. (b) test for significance of regression using . (c) find a 90.0% confidence interval estimate on the slope. (d) test the hypothesis versus using .
