13-51. An experiment was conducted to investigate leaking current in a SOS MOSPETS device. The purpose of the experi ment was to investigate how leakage current varies as the chan nel length changes. Four channel lengths were selected. For each channel length, five different widths were also used, and width is to be considered a nuisance factor. The data are as follows: Channel Width Length 1. 0.7 0.8 :0.8 0.9 1.0 2 0.8 0.8 0.9 0.9 1.0 0.9. 1.0 *1.7 2.0 40 A 1.0 1.5 2.0 3.0 20.0 (a) Test the hypothesis that mean leakage voltage does not depend on the channel length using o = 0.05. (b) Analyze the residuals from this experiment. Comment on the residual plots. (c) The observed leakage voltage for channel length 4 and width 5 was erroneously recorded. The correct observation is 4.0. Analyze the corrected data from this experiment Is there evidence to conclude that mean leakage voltage increases with channel length
