X value 10, 8, 13, 9, 11, 14, 6, 4, 12, 7, 5

Y value 9.14, 8.13, 8.75, 8.76, 9.25, 8.11, 6.14, 3.09, 9.13, 7.25, 4.73

Use a =.05 Attached is the linear correlation along with the scatter plot

Determine whether there is sufficient evidence to support the claim of a linear correlation between the two variables (A, B, C, or D).

(a) There is insufficient evidence to support the claim of a nonlinear 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

(d) There is insufficient evidence to support the claim of a linear correlation between the 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, or D)

(A) The scatterplot reveals a distinct pattern that is not a straight-line pattern.

(b) The scatterplot does not reveal a distinct pattern

(a) The scatterplot reveals a distinct pattern that is a straight-line pattern with negative slope.

(d) The scatterplot reveals a distinct pattern that is a straight-line pattern with positive slope
