Answer: 0.753.
Step-by-step explanation:
The value of the correlation coefficient is denoted by 'r'. It is used to describe the strength and direction of the relationship between two variables.
Given: The relationship between the number of hours a person practices a task and the time it takes them to complete the task is calculated to have R-sq = 56.7%.
= 0.567
Then, [tex]r=\sqrt{R^2}[/tex]
[tex]=\sqrt{0.567}\approx0.753[/tex]
Hence, the value of the correlation coefficient is 0.753.
