Answer 1

on a graphing calculator, press stat, press 1 for edit. in list 1, enter all values. press stat again, go right to calc. press 1 for 1-var stats. press enter until it gives you the freq list. this will give you a list of helpful information on the data you entered in the list, including mean, median, and standard deviation.
mean: 279230.3
median: 255729
standard deviation (Sx): 135007.18
to find the range, subtract the smallest value (min) from the greatest value (max). these can also be found on the freq list. 492193-45815=446378.
therefore the range is 446378.
hope this helps!
