Use the given data set to complete parts (a) through (c) below. (Use =0.05). x y 10 9.15 8 8.14 13 8.74 9 8.76 11 9.26 14 8.09 6 6.13 4 3.11 12 9.13 7 7.27 5 4.75 (a) Construct a scatterplot. (b) Find the linear correlation coefficient, r, then determine whether there is sufficient evidence to support the claim of a linear correlation between two variables. The linear correlation coefficient is r=___ (round to the decimal places as needed.) 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 sufficient evidence to support the claim of nonlinear correlation between the two variables. (b) There is insufficient 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. (d) There is insufficient evidence to support the claim of a linear correlation between two variables. 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) (b) (c) (d) The scatterplot reveals a distinct pattern that is straight- line pattern slope. The scatterplot does not reveal a distinct pattern. The scatterplot reveals a distinct pattern that is not a straight-line pattern. The scatterplot reveals a distinct pattern that is a straight-line pattern with negative slope
