Explanation / Answer

Find the median of {1,1,2,3,5,9,7,12} So you start by putting the numbers inorder:{1,1,2,3,5,7,9,12} Then you look for the middle number in the sequence: so forthis the middle numbr is between 3 and 5. So there is no middle number whenever there is an even amountof numbers??? Wrong The middle number is the average of 3 and 5, so it is 4
Now lets do yours Order them: (17, 22, 26, 27, 27, 27, 27, 29, 29, 29, 29,29...} There are 20 numbers and the "middle number" will be number(n+1)/2, so it is number 10.5 here This between 29 and 29, so the average of theseis...29
Hope that helps
