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.
