For the most recent seven years, the U.S. Department of Education reported the following number of bachelor's degrees awarded in computer science: 4,033; 5,652; 6,407; 7,201; 8,719; 11,154; 15,121. What is the annual arithmetic mean number of degrees awarded?
About 12,240
About 8,327
About 6,217
About 15,962
12,240
To find the annual arithmetic mean number of degrees awarded, you need to add up the number of degrees awarded for each year and then divide it by the number of years.
In this case, you have the following numbers of degrees awarded for each year:
4,033; 5,652; 6,407; 7,201; 8,719; 11,154; 15,121.
To find the annual arithmetic mean, you need to add these numbers together and then divide by 7 (since there are 7 years of data):
4,033 + 5,652 + 6,407 + 7,201 + 8,719 + 11,154 + 15,121 = 58,287
58,287 divided by 7 = 8,326.71
Rounding to the nearest whole number, the annual arithmetic mean number of degrees awarded is about 8,327.
So the correct answer is "About 8,327."
