Ara's mean test score will increase the most because they got a perfect score on their latest test, bringing their mean score closer to 100.

The range of the speeds of the fastest steel roller coasters in Europe is
_______ mph. The range of the speeds of the fastest steel roller coasters in North America is
_______ mph.
To find the range of the speeds of the fastest steel roller coasters on both continents, you need to subtract the lowest speed from the highest speed in each group.
For the speeds of the fastest steel roller coasters in Europe:
The lowest speed is 74 mph (from the stem-and-leaf plot), and the highest speed is 91 mph (from the stem-and-leaf plot).
The range is 91 - 74 = 17 mph.
For the speeds of the fastest steel roller coasters in North America:
The lowest speed appears to be 85 mph (from the table), and the highest speed is 128 mph (also from the table).
The range is 128 - 85 = 43 mph.
Therefore, the range of the speeds of the fastest steel roller coasters in Europe is 17 mph, and the range of the speeds of the fastest steel roller coasters in North America is 43 mph.
For the speeds of the fastest steel roller coasters in Europe:
The lowest speed is 74 mph (from the stem-and-leaf plot), and the highest speed is 91 mph (from the stem-and-leaf plot).
The range is 91 - 74 = 17 mph.
For the speeds of the fastest steel roller coasters in North America:
