11. Tri-State Smokers. A Gallup Poll of U.S. adults indicated that Kentucky is the state with the highest percentage of smokers (Gallup website). Consider the following example data from the Tri-State region, an area that comprises northern Kentucky, southeastern Indiana, and southwestern Ohio. State Smoker Non-Smoker Kentucky Indiana 47 176 32 134 Ohio 39 182 Total: 118 492 a. Use the data to compute the probability that an adult in the Tri-State region smokes. b. What is the probability of an adult in each state of the Tri-State region being a smoker? Which state in the Tri-State region has the lowest probability of an adult being a smoker?

10. Code Churn. Code Churn is a common metric used to measure the efficiency and productivity of software engineers and computer programmers. It's usually mea as the percentage of a programmer's code that must be edited over a short period of time. Programmers with higher rates of code churn must rewrite code more often because of errors and inefficient programming techniques. The following table displays sample information for 10 computer programmers. sured Total Lines of Code Number of Lines of Code Programmer Written Requiring Edits 4,589 2,780 12,080 3,780 1,890 4,005 5,785 1,052 3,872 4,125 Liwei 23,789 17,962 31,025 26,050 19,586 24,786 24,030 14,780 30,875 21,546 Andrew Jaime Sherae Binny Roger Dong-Gil Alex Jay Vivek a. Use the data in the table above and the relative frequency method to determine probabilities that a randomly selected line of code will need to be edited for each programmer. b. If you randomly select a line of code from Liwei, what is the probability that the line of code will require editing? c. If you randomly select a line of code from Sherae, what is the probability that the line of code will not require editing? d.
