An ecоnоmist wаnts tо determine the relаtion between one’s FICO score, x, аnd the interest rate of a 36-month auto loan, y. See the sample of data below which represent the interest rate (in percent) a bank would offer on a 36-month auto loan for various FICO scores. Answer the questions that follow. Showing work in the text boxes is required to receive credit or partial credit. Using Copy/Paste, Cut/Paste, or Right Click Copy is not allowed. Credit Score Interest Rate (%) 545 18.982 595 17.967 640 12.218 675 8.612 705 6.680 750 5.150 a) Which variable is the explanatory variable and which variable is the response variable? b) Find the correlation coefficient for the above data. Also, interpret its meaning in a sentence in context of the problem. c) Find the least-squares regression equation. d) Using the least-squares regression equation, predict the value of the response variable when the explanatory variable is 675. Calculate the residual when the explanatory variable of the data is 675. e) Determine the coefficient of determination. Also, interpret it in a sentence in context of the problem. f) Determine the standard error of the estimate . g) Determine the value of . Show all of your work. h) If we assume that the residuals are normally distributed, test whether a linear relation exists or not between credit score and interest rate, at the significance level of α = 0.05. Show all of your work. State the hypothesis: Find the critical values: Compute the value of the test statistic: Determine your decision: Write your conclusion: Note: For this last part you could also choose to use the p-value approach instead, the steps of this approach are listed for the above 2 questions.
