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.
OA. There is sufficient evidence to support the claim of a linear correlation between the two variables.
OB. There is sufficient evidence to support the claim of a nonlinear correlation between the two variables.
OC. There is insufficient evidence to support the claim of a nonlinear correlation between the two variables.
OD. There is insufficient evidence to support the claim of a linea correlation between the two variables.
A. The scatterplot reveals a distinct pattern that is not a straight-line pattern.
B. The scatterplot reveals a distinct pattern that is a straight-line pattern with positive slope.
OC. The scatterplot reveals a distinct pattern that is a straight-line pattern with negative slope.
OD. The scatterplot does not reveal a distinct pattern.
