Answer:
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](https://img.qammunity.org/2022/formulas/mathematics/college/4asfvqzxaujkj4k9tu9li15k1fyag433dq.png)
