The accompanying table shows the maximum weights (in kilograms) for which one repetition of a half squat can be performed and the times (in seconds) to run a 10-meter sprint for 12 international soccer players. Complete parts (a) through (d) below. Click here to view the data table. Click here to view the table of critical values for the Pearson correlation coefficient. (a) Display the data in a scatter plot. Choose the correct graph below. O A. . .

(Round to three decimal places as needed.) (c) Describe the type of correlation, if any, and interpret the correlation in the context of the data. There is V linear correlation.

In eight for which one repetition of a half squat can be performed cause time to run a 10-meter sprint to decrease. (d) Use the table of critical values for the Pearson correlation coefficient to make a conclusion about the correlation coefficient. Let a = 0.01. The critical value is. Therefore, there sufficient evidence at the 1% level of significance to conclude that V between the maximum weight for which one repetition of a half squat can be performed and time to run a 10-meter sprint.

Interpret the correlation. Choose the correct answer below. O A. Increases in the maximum weight for which one repetition of a half squat can be performed cause time to run a 10-meter sprint to increase. O B. As the maximum weight for which one repetition of a half squat can be performed increases, time to run a 10-meter sprint tends to increase. O C. As the maximum weight for which one repetition of a half squat can be performed increases, time to run a 10-meter sprint tends to decrease. O D. Based on the correlation, there does not appear to be any relationship between the maximum weight for which one repetition of a half squat can be performed and time to run a 10-meter sprint. O E. Based on the correlation, there does not appear to be a linear relationship between the maximum weight for which one repetition of a half squat can be performed and time to run a 10-meter sprint. O F. Increases in the maximum weight for which one repetition of a half squat can be performed cause time to run a 10-meter sprint to decrease.
