  • (C) Is more than 1 choice correct in either (a) or (b)? Explain and please show the work I want to know how you got the answer!
  • Standard deviation measures the "RMS" average distance of the numbers from the mean. How far apart they are. Zero standard deviation means all the numbers are the same. So pick any number from 0 to 10 and repeat it four times. For (b) you need to spread the numbers out. The most spread out they can be is to have them at each end: 0 and 10. They will be furthest from the mean if the mean is in the middle, so you need the same number of numbers at 0 as at 10.
  • a) 1,1,1,1 B) 0,0,10,10
  • Can the work be shown for the answer: 0,0,10,10 Thanks
