Answer:
B
Step-by-step explanation:
Let's put each list of the yearly rainfall totals in order from least to greatest.
The yearly rainfall totals in inches for Seattle are:
23.78 , 32.46 , 40.30 , 45.79 , 49.42 , 55.14
The median is the average of the two middle numbers in this list.
The median yearly rainfall for Seattle = (40.30 + 45.79)/2 in
The median yearly rainfall for Seattle = 43.045 in
The yearly rainfall totals in inches for Las Vegas are:
2.33 , 3.72 , 3.84 , 4.11 , 5.62 , 8.79
The median yearly rainfall for Las Vegas = (3.84 + 4.11)/2 in
The median yearly rainfall for Las Vegas = 3.975 in
The difference between the median yearly rainfall for Seattle and Las Vegas = 43.045 in - 3.975 in
The difference between the median yearly rainfall for Seattle and Las Vegas = 39.07 in
