What is the average, or mean, weight of the upper-class men offensive players? provide your answer with 3 sig figs.

1) 311 pounds

2) 315 pounds

3) 290 pounds

4) 318 pounds

311 pounds

Step-by-step explanation:

Here, we are to calculate the average weight of the upper-class men offensive players

To calculate this, we need to sum up all the weights and divide by their count

Mathematically, that would be;

Average weight = (322+290+321+326+330+315+311+292+290) / 9 = 2,797/9 = 310.77778

Now this written in 3 significant figures would be 311 pounds
