A large manufacturer of batteries knows that, historically, 10% of its batteries come off the production line defective, and the remaining 90% of batteries come off the production line in working condition. Conduct a simulation to estimate how many batteries the company needs to pull off the production line in order to be sure of ending up with 10 working batteries.

Describe how you will use a random number table to conduct this simulation.

Since 10% of the batteries come off of the production line defective and 90% of the batteries come off of the line in working condition, we can look at one digit at a time. Assign the digits: 1-9 = working. Start at the first digit in the first row, go across one digit at a time, looking for the digits 1-9, which are indicative of working batteries. Count the number of times the digits 1-9 come up until you have 10. Count the number of digits that the trial took to obtain 10 of the desired digits.
