Help pls I have no clue how

Answer 1

Explanation:

By using regression line calculator,

Equation of the regression line from the data given,

y = -0.38993x + 26.95184

Here, y = weekly hours of sport

x = Time to run

For x = 50 minutes,

y = -0.38993(50) + 26.95184

= 7.45534

≈ 8

Since, slope of the given regression line is negative, correlation will be negative (n).
