Which value of r indicates a stronger correlation: r=D0.717 or r= -0.875? Explain your reasoning. Choose the correct answer below. O A. r= -0.875 represents a stronger correlation because 0.717> -0.875. O B. r=0.717 represents a stronger correlation because -0.875 > 0.717. O C. r 0.717 represents a stronger correlation because 0.717> -0.875. O D. r= -0.875 represents a stronger correlation because -0.875> 0.717.

EQuestion Help 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 0.899. Remove the data entry for the man who is 50 years old and has a systolic blood pressure of 200 millimeters of mercury from the data set and find the new correlation coefficient. Describe how this affects the correlation coefficient r. Use technology E Click the icon to view the data set.

The given figure displays the relationship between golfers' scores on the first and second rounds of the 2019 Masters Tournament.   The correlation is ?=0.283.is �=0.283. The provided figure gives data on number of boats registered in Florida and the number of manatees killed by boats for the years 1977 to 2018.   The correlation is ?=0.919.is �=0.919. Explain in simple language why knowing only these correlations enables you to say that prediction of manatee deaths from number of boats registered by a regression line will be much more accurate than prediction of a golfer's second-round score based on that golfer's first-round score.
