Question

For every additional minute it takes to run the 1500 m the estimated oxygen consumption rate decreases by 3.31.

There is good evidence that there is a relationship between oxygen consumption and the run time.

A person who runs 1500 m in 10 minutes would have an estimated oxygen consumption rate of about 50.

The slope is 82.42.

The fitted regression line is approximately Y = 82.423.31(runtime)

For every additional minute it takes to run the 1500 m the estimated oxygen consumption rate decreases by 3.31.

There is good evidence that there is a relationship between oxygen consumption and the run time.

A person who runs 1500 m in 10 minutes would have an estimated oxygen consumption rate of about 50.

The slope is 82.42.

The fitted regression line is approximately Y = 82.423.31(runtime)

Given regression equation is: 82.42 - 3.31(run time). Comparing it with slope intercept form of equation which is:

Y = mX + C, we have, C = Intercept = 82.42, X = run time and thus, m = slope = 3.31

Thus, it is not correct that the slope is 82.42 because slope = 3.31

Hence, the correct answer is option d. The slope is 82.42 as it is not correct and the question asked is which option is not correct.

All other options are correct.
