To find the annual arithmetic mean, we need to add up all the degrees awarded and divide by the number of years (7 in this case). 
Total degrees awarded = 4,033 + 5,652 + 6,407 + 7,201 + 8,719 + 11,154 + 15,121 = 58,287 
Annual arithmetic mean = 58,287 / 7 = 8,326.71, which is closest to 8,327 (option B).
