12. A game show uses a spinner that they claim is equally likely to stop in each of five sections, one which is labeled "JACKPOT". However, in the last twenty spins, the spinner did not stop in the section labeled "JACKPOT". Which of the following is not a correct step if a player wanted to carry out a simulation to estimate the probability that the spinner would not stop in the section labeled "JACKPOT" in twenty spins of the spinner, if we assume that each section of the spinner is equally likely to appear? a. Ask the question, "What is the probability that the spinner would not stop in the section labeled JACKPOT in twenty spins?" b. Perform two hundred trials to see how many times all twenty of the random numbers generated represent the simulated spinner not stopping in the section labeled "JACKPOT". c. Assign the digits 1, 2, to represent the spinner stopping in the section labeled "JACKPOT" and 3, 4, 5, 6, 7, 8, 9, 10 to represent not stopping in the section labeled "JACKPOT". Generate 20 random numbers and count the number of times the simulated spinner did not stop in the section labeled "JACKPOT". d. If the number of times all twenty simulated spins did not stop in the section labeled "JACKPOT" was extremely small and close to zero, than the claim that each section is equally likely is probably true.

9. The teachers at a local high school were surveyed. Two of the variables recorded for the 150 teachers were
housing status and length of service. Housing status was recorded as owning or renting your residence, while
length of service was classified as a new teacher with less than 5 years of service or as an experienced
teacher who has at least 5 years of service. The following table summarizes the responses. Based on the
responses, what is the probability that a randomly selected teacher from this school is a renter if we know the
teacher has less than 5 years of teaching experience?
