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 the two variables.

the linear correlation coefficient is r =

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 a linear correlation between the two variables.

b- there is insufficient evidence to support the claim of a linear correlation between the two variables.

c- there is insufficient evidence to support the claim of a nonlinear correlation between the two variables.

d- there is sufficient 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 astraight-line pattern with positive slope.

b- the scatterplot reveals a distinct pattern that is not astraight-line pattern.

c- the scatterplot reveals a distinct pattern that is astraight-line pattern with negative slope.

d- the scatterplot does not reveal a distinct pattern.
