The ages​ (in years) of 10 men and their systolic blood pressures​ (in millimeters of​ mercury) are shown in the attached data table with a sample correlation coefficient r of 0.910. Remove the data entry for the man who is 49 years old and has a systolic blood pressure of 199 millimeters of mercury from the data set and find the new correlation coefficient. Describe how this affects the correlation coefficient r. Use technology.   ​Age, x Systolic blood​ pressure, y   16 110   26 122   39 142   44 132   49 199   64 185   72 199   31 130   56 174   23 117 Click the icon to view the data set.

Assume that you have paired values consisting of heights (in inches) and weights (in Ib) from 40 randomly selected men. The linear correlation coefficient r is 0.563. Find the value of the coefficient of determination. What practical information does the coefficient of determination provide? Choose the correct answer below. A. The coefficient of determination is 0.317. 68.3% of the variation is explained by the linear correlation, and 31.7% is explained by other factors. O B. The coefficient of determination is 0.683. 31.7% of the variation is explained by the linear correlation, and 68.3% is explained by other factors. O C. The coefficient of determination is 0.683. 68.3% of the variation is explained by the linear correlation, and 31.7% is explained by other factors. O D. The coefficient of determination is 0.317. 31.7% of the variation is explained by the linear correlation, and 68.3% is explained by other factors.

Which value of r indicates a stronger correlation: r= 0.815 or r= - 0.933? Explain your reasoning. Choose the correct answer below. O A. r= - 0.933 represents a stronger correlation because 0.815> - 0.933. O B. r= 0.815 represents a stronger correlation because 0.815 > - 0.933. OC. r= - 0.933 represents a stronger correlation because | - 0.933|> |0.815|. O D. r= 0.815 represents a stronger correlation because |-0.933|> |0.815|.
