A Correct answer
Explanation

The average is calculated by finding the sum of all heights (170*2 + 172*4 + 176*6 + 178*8 + 180*4) and dividing by the total number of players (24). The sum is 4228, and 4228 / 24 equals approximately 176.166, which rounds to 176.2.

AI explanation

To find the average, multiply each height by its frequency and sum them, which gives 340 plus 688 plus 0 plus 1056 plus 1424 plus 720, totaling 4228. Divide this total by the 24 football players to get an average height of 176.2 cm.
