Consider a sample with data values of 10,21,13,19, and 15 . (a) Compute the mean and median. Mean Median = (b) Consider a sample whe date values 10, 21, 13, 19, 15, and 13. How would you expect the mean and medan for these sample data to compare to the mean and median for part a (higher, lower, or the same)? (i) Both the mean and median will decrease. (ii) The mean will increase while the median wal decrease. (iii) The mean will increase while the median wa increase. (iv) Both the mean and median will increase. (v) Both the mean and median will stay the same. Compute the mean and median for the sample data 10, 21, 13, 19, 15, and 13. If required, round your answers to one decimat place. Mean Median =
