The amount of variance for y that is predicted by its relationship with x is 64%.
<h3>
How much variance is predicted?</h3>
Variance measures the rate of dispersion of a data point around the dataset. It can be calculated by finding the square of the standard deviation of a dataset. Variance measures the variation of a data set.
Correlation is a statistical measure used to measure the linear relationship that exists between two variables. The greater the correlation coefficient is closer to one, the greater the linear relationship that exists between the two variables. A positive correlation occurs when the two variables move in the same direction.
Variance = (correlation coefficient²) x 100
(0.80²) x 100
0.64 x 100 = 64%

Answer:
35
Step-by-step explanation:
10/12 of an hour/60 minutes = 50 minutes so they spent that amount of time doing daily exercises
1/4 of an hour/60 minutes = 15 minutes so they spend that time hiking
subtract the 15 mins of hiking from the total 50 of exercises = 35 for other body exercises
