Use the following for question 8 to 10. Silicon-germanium alloys have been used in certain types of solar cells. Researchers investigated how germanium (Ge) concentration affected the Fermi level position (eV). Assume all observations are independent. We have the following results. Simple linear regression results Dependent Variable : Fermi level Independent Variable : Ge Fermi level = 0.721786 - 0.43268475 Ge Sample size : 13 R (correlation coefficient) = -0.073757327 R-sq = 0.80156604 Estimate of error standard deviation = 0.073757327...
