Question Answered step-by-step Would you expect a positive or negative correlation between the… Would you expect a positive or negative correlation between the model mileage and price? 2 .Is mileage the independent or dependent variable? 3.What is your regression equation for the best fit line? Be sure to confirm your equation from Excel with your TI-84. 4. dentify the values for the following from Excel.Slope of regression line: y-intercept of regression line: Coefficient of determination (r2): Linear correlation coefficient (r): Interpret the linear correlation coefficient (r). Does it agree with the strength and slope of your scatter plot? Determine if there is a significant negative linear correlation at the 10% level of significance. State the null and alternate hypotheses to test for a significant negative linear correlation. Determine the critical value and sketch (or describe) the rejection region. Record the test statistic (t) from your Excel printout. Use the traditional method to make a conclusion, explain why, and interpret in context. Based on your conclusion from #4d, is this regression equation appropriate for predicting the price of a Civic? If so, for which mileages is it appropriate? If appropriate, use the regression equation to determine the sale price for a Honda Civic with 100,000 miles on it. Interpret the coefficient of determination (r2) in context.
