Priya asked each of five friends to attempt to throw a ball in a trash can until they succeeded. She recorded the number of unsuccessful attempts made by each friend as: 1, 8, 6, 2, 4. Priya made a mistake: The 8 in the data set should have been 18. How would changing the 8 to 18 affect the mean and median of the data set?

1.) The mean would decrease and the median would not change
2.) The mean would increase and the median would not change.
3.) The mean would decrease and the median would increase
4.) The mean would increase and the median would increase.
