Answer 2

The best estimate of the population mean for heart rate among football players is of 71.4 beats per minute.

Explanation:

The best estimate for the population mean is the sample mean.

Sample mean:

Sum of all values in the sample divided by 10(size of the sample). So

`\overline{x} = (62+74+74+64+76+64+80+76+68+76)/(10) = 71.4`

The best estimate of the population mean for heart rate among football players is of 71.4 beats per minute.
