There is linear correlation.I no a weak positive a strong positive a weak negative a perfect negative a strong negative . a perfect positive I Interpret the correlation. Choose the correct answer below. 0 . 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. O B. As the maximum weight for which one repetition of a half squat can be performed increases, time to run a llmeter sprint tends to increase. @1 C. 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 D. 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 E. As the maximum weight for which one repetition of a half squat can be performed increases, time to run a illmeter sprint tends to decrease. O F. 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. {d} Use the table ofcritical values for the Pearson correlation coefcient to make a conclusion about the correlation coefcient. Let a: [1.01. The critical value is |:. Therefore, there |:1| sufcient evidence at the 1% level of signicance to conclude that 'F between the maximum weight for which one repetition of a half squat can be performed and time to run a \"IImeter sprint. [Round to three decimal places as needed} 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.
