y ≈ 31.548
x + 31.548
If someone were to meditate for 20 minutes, the regression line would predict that it would take them approximately 31.548 minutes to fall asleep.
After calculating the regression line using the provided data points, we get:
r ≈ -0.899
y ≈ 33.504
x + 33.504
Therefore, if someone were to meditate for 20 minutes, the regression line would predict that it would take them approximately 33.504 minutes to fall asleep.
After recalculating the regression line using the data provided, we get:
r ≈ -0.946
y ≈ 35.83
x + 35.83
Therefore, if someone were to meditate for 20 minutes, the regression line would predict that it would take them approximately 35.83 minutes to fall asleep.
