Question

A study on how the time of exercise affects heart rate had the following output

Simple Linear regression results:
Dependent Variable: Heart Rate
Independent Variable: Exercise time
Sample size: 81
R (correlation coefficient) = 0.4188
R-sq = 0.1754
Estimate of error standard deviation: 0.32416
Parameter estimates:

Parameter	Estimate	Std. Err.	DF	T-Stat	P-Value
Intercept	1.80938	1.9352	79	0.935	0.3524
Slope	0.4752395	0.11594	79	4.099	<0.0001

According to the output, if I exercise for time=163, what should be my heart rate?
Use 4 decimal places

After exercising everybody has different heart rates, which means there is a lot of variability in heart rates. How much of that variability is explained by exercise time?
Use 4 decimal places
