To find the median yearly rainfall for Seattle and Las Vegas, we first need to list each city's rainfall totals and then determine the median.

Seattle, WA Rainfall Totals:

  • 2010: 45.79
  • 2011: 32.46
  • 2012: 55.14
  • 2013: 40.30
  • 2014: 23.78
  • 2015: 49.42

Arranging these in order:

  • 23.78
  • 32.46
  • 40.30
  • 45.79
  • 49.42
  • 55.14

Since there are six values (an even number), the median is the average of the two middle numbers: Median = (40.30 + 45.79) / 2 = 43.045 in.

Las Vegas, NV Rainfall Totals:

  • 2010: 3.72
  • 2011: 5.62
  • 2012: 4.11
  • 2013: 8.79
  • 2014: 2.33
  • 2015: 3.84

Arranging these in order:

  • 2.33
  • 3.72
  • 3.84
  • 4.11
  • 5.62
  • 8.79

Again, since there are six values (an even number), the median is the average of the two middle numbers: Median = (3.84 + 4.11) / 2 = 3.975 in.

Now, calculate the difference between the median rainfall amounts: Difference = Median Seattle - Median Las Vegas Difference = 43.045 in. - 3.975 in. Difference = 39.07 in.

Therefore, the difference between the median yearly rainfall for Seattle and Las Vegas is 39.07 inches.
