C is correct

Explanation:

Answer 2

To find the mean number of ice chests in a section, we need to add up the number of ice chests in each of the 8 sections and then divide by the number of sections:

(45 + 57 + 30 + 62 + 57 + 45 + 30 + 57) / 8 = 383 / 8 = 47.875

Therefore, the mean number of ice chests in a section is 47.875, which is answer choice C.
