Question 292408: Could you show me how to do this problem?
-Design and conduct a simulation to determine the ages of 20 licensed drivers chosen ar random in the United States.
And then the table that came with it looks like this:
Licensed drives in the United States, by Age
a-<20, 20-29, 30-39, 40-49, 50-50, 60-60, 70-79, >/_80
P(a)-0.051, 0.176, 0.211, 0.211, 0.156, 0.096, 0.070, 0.029

You can put this solution on YOUR website! Could you show me how to do this problem?

-----------------------
You are given 8 age intervals (0,19),(20,29)....(80,infinity)
You are give the know percentage of drivers in each age interval
--------------------------
To simulate this problem I used the "randint" function of my Ti-84.
Enter "randint(0,999,20)" which generates 20 integers between
0 and 999.
-----
0-51 represents those in interval (0,19)
52-228 represents those in interval (20,29)
229-440 represents those in interval (30-39)
....
---
970-999 represents those in interval (80,inf)
====================================================
I count the number in the list that fit each age interval
I repeat the command "randint(0,999,20), count again, and enter the
results.
I do this whatever number of times you want to, then determine the percentages in each of the intervals.
I compare those percentages to the percentages in the data you were given.
