Which scatter plot shown has the strongest negative correlation?

Let x be the average number of employees in a group health insurance plan, and let y be the average administrative cost as a percentage of claims. x 3 7 15 32 75 y 40 35 30 26 18 (a) Make a scatter diagram of the data and visualize the line you think best fits the data.  Flash Player version 10 or higher is required for this question. You can get Flash Player free from Adobe's website.   (b) Would you say the correlation is low, moderate, or strong? positive or negative? strong and negative moderate and negative   strong and positive low and negative low and positive moderate and positive (c) Use a calculator to verify that Σx = 132, Σx2 = 6932, Σy = 149, Σy2 = 4725, and Σxy = 2997. Compute r. (Round your answer to three decimal places.)r =  As x increases, does the value of r imply that y should tend to increase or decrease? Explain. Given our value of r, we cannot draw any conclusions for the behavior of y as x increases. Given our value of r, y should tend to…

Assume that you have paired values consisting of heights​ (in inches) and weights​ (in lb) from 40 randomly selected men. The linear correlation coefficient r is 0.567. Find the value of the coefficient of determination. What practical information does the coefficient of determination​ provide?       Question content area bottom Part 1 Choose the correct answer below.     A. The coefficient of determination is 0.321. 32.1​% of the variation is explained by the linear​ correlation, and 67.9​% is explained by other factors.   B. The coefficient of determination is 0.679. 67.9​% of the variation is explained by the linear​ correlation, and 32.1​% is explained by other factors.   C. The coefficient of determination is 0.321. 67.9​% of the variation is explained by the linear​ correlation, and 32.1​% is explained by other factors.   D. The coefficient of determination is 0.679. 32.1​% of the variation is explained by the linear​ correlation, and 67.9​% is…

What effect does an outlier have on a correlation coefficient? Would it increase, decrease or stay the same?

Using technology, what is the correlation coefficient? The weight (in pounds) and height (in inches) for a child were measured every few months over a two-year period. The results are given in the table. O -0.997 O -0.503 Weight (x) 8. 12 18 24 30 32 35 37 40 O 0.503 Height (y) 22 23 26 30 32 33 5 36 38 O 0.997
