Assume the following daily closing for the Dow Jones Industrial Average:
Day DJIA Day DJIA
1 12,010 7 12,220
2 12,100 8 12,130
3 12,165 9 12,250
4 12,080 10 12,315
5 12,070 11 12,240
6 12,150 12 12,310
a.
To find the average closing value for the Dow Jones Industrial Average for the given days, you need to add up all the closing values and divide by the number of days.
Here's how you can calculate it:
- Add up the closing values for each day: 12,010 + 12,100 + 12,165 + 12,080 + 12,070 + 12,150 + 12,220 + 12,130 + 12,250 + 12,315 + 12,240 + 12,310 = 145,980.
- Divide the sum by the number of days, which is 12: 145,980 / 12 = 12,165.
Therefore, the average closing value for the Dow Jones Industrial Average for the given days is 12,165.
