12. I gave a test with a misprinted question which everyone in the class got wrong. When going over the test, someone pointed out the misprint and I added 5 points to everyone's grades. How did this change affect the original mean and the median that I had calculated before passing them back? 13. Your company, STAT TRACK, has launched a new website. After the first week, you calculated the mean and median for the number of hits you get per day. It was pretty dismal. You hired a web designer whose promises to double the number of hits actually came true. How did this change affect the original mean and the median that you had calculated before hiring the designer? 14. A survey reported the ages of 15 randomly selected customers at a local Best Buy: 23, 21, 29, 24, 31, 21, 48, 27, 23, 188, 24, 32, 33, 19, 59 How should you treat the data? 15. You have a new job coaching a Long Jump Team. (Looks like STAT TRACK didn't work out for you.) After the first month, the athletes' performance has changed. James can now jump 0.15m further, Mike and Jack can jump 0.06m further. Here are all the results after a month: James: +0.15m Tom: +0.11m Mike: +0.06m Jack: +0.06m Bob: + 0.12m Sam: -0.56m Oh no! Sam got worse. Sam's father has asked that you be fired. Is Sam's result an outlier? How does it change the mean and the median? Defend your job
