To find the arithmetic mean, we need to add up all the numbers and then divide by the total number of years. So, adding up:
4,033 + 5,652 + 6,407 + 7,201 + 8,719 + 11,154 + 15,121 = 58,287
Dividing by 7 (the total number of years) gives us:
58,287/7 = 8,326.71
Rounding off to the nearest whole number, we get about 8,327. Therefore, the best choice is B, which is about 8,327.
