Q2 (7 pt.): The following data show the accompanying data on x = current density (mA/cm²) and y = rate of deposition (um/min). Do you agree with the claim by the article's author that "a linear relationship was obtained from the tin-lead rate of deposition as a function of current density"? Explain your reasoning. x 20 40 60 80 y 0.24 1.20 1.71 2.22 a. (0.5 pt.) Graph y versus x. (you can use Excel and bring the output of Excel for this part) b. (2 pt.) Determine the coefficient parameters (Bo, B1) c. (1 pt.) Do you agree with the claim by the article's author that "a linear relationship was obtained from the tin-lead rate of deposition as a function of current density"? Explain your reasoning. (a = 5% or confidence level = 95%) d. (1.5 pt.) Determine (1 - a)% confidence interval for the slope of regression line e. (1 pt.) Calculate R-Square f. (1 pt.) Bring the output of Excel for this regression modeling and highlight the R-Square and regression parameters.
