Suppose 10% of the flights arriving at an airport arrive early, 60% arrive on time, and 30% arrive late. Valerie use the random number table to find the experimental probability that of 5 flights, at least 2 will arrive late. The digit 0 represents flights arriving early. The digits 1, 2, 3,4, 5, and 6 represent flights arriving on time. The digits 7, 8, and 9 represent flights arriving late.

1. You have to use a random number table to choose 5 random numbers. Do this at least 10 times.

You might get numbers like

57014 in this case 7 represents arrives late.

the next number might be

03698 in this case 8 and 9 represents arrive late so you have
2

After you finish the experiment you average your numbers together.

Theoretical would be 30% of 5 or 1.5 would arrive late. Test your experimental against this number.
