b. Find the linear correlation coefficient, r, then determine whether there is sufficient evidence to support the claim of a linear correlation between the two variables. The linear correlation coefficient is r= ? (Round to three decimal places as needed.) Using the linear correlation coefficient found in the previous step, determine whether there is sufficient evidence to support the claim of a linear correlation between the two variables. Choose the correct answer below. A. There is insufficient evidence to support the claim of a linear correlation between the two variables. B. There is sufficient evidence to support the claim of a nonlinear correlation between the two variables. C. There is sufficient evidence to support the claim of a linear correlation between the two variables. Your answer is correct. D.There is insufficient evidence to support the claim of a nonlinear correlation between the two variables. c. Identify the feature of the data that would be missed if part (b) was completed without constructing the scatterplot. Choose the correct answer below. A.The scatterplot reveals a distinct pattern that is a straight-line pattern with positive slope. B.The scatterplot reveals a distinct pattern that is not a straight-line pattern. Your answer is correct. C.The scatterplot reveals a distinct pattern that is a straight-line pattern with negative slope. D.The scatterplot does not reveal a distinct pattern.
