1. Implement the Statistician class from Project 2 on page 95, but include a new method that returns the median value of all the numbers. The median is a number that is greater the than or equal to at least half of the numbers and is also less than or equal to at least half of the numbers. Because of the new median calculation, the Statistician will need to keep track of all the numbers, perhaps using an array. The median calculation will be easiest if you keep these numbers in order from smallest to largest.
