Find the inear correlation coeficient r, then Sect (Round to three decimal places as needed ) determine whether there is suticient evidence to support the claim of a linear correlation between the two variables The linear correlation coeficient is r Using the linear correlation coefficient found the two variables Choose the correct answer below in the previous step, determine whether there is sufficient evidence to support the claim of a linear correlation between st 11 OA. There is insuficient evidence to support the claim of a nonlinear correlation between the two va O B. There is sufficient evidence to support the claim of a nonlinear correlation between the two variables C. There is insufficient evidence to support the claim of a linear correlation between the two variables O D. There is sufficient evidence to support the claim of a linear correlation between the two variables MA C.Idensily the feature of the data that would be missed it part (b) was completed without constructing the scatterplot Choose the correct answer below 1.2 O A. The scatterplot does not reveal a perfect stralight-line pattorn, and contains one outlier ○ B. The scatterplot reveals a perfect straight-line pattern, except for the presence of one oder O C. The scaterplot reveals a pertect straight -ine patterm and does not contain any outlers 0 D. The scatterplot does not reveal a perfect straight-line pattern Se Unit

Answer 1

b) r= 0.817

Since Pvalue= 0.002 <0.05 level of significance therefore significant.

There is sufficient evidence to support the claim of linear correlation between two variables. OPTION D

c)

The scatter plot reveals a perfect straight line pattern , except for the presence of one outlier. OPTION B
