Answer:D. 10

Researchers randomly surveyed people at two amusement parks, Funland and Thrillville, to find out how many times they visit the
STALIN [3.7K]

On average, people visit Thrillville 2 more times per year than Funland.

<h3><u>Averages</u></h3>

To determine how many more times per year, on average, do people visit Thrillville than Funland, the following calculation must be performed:

  • Funland: 4,1,2,1,5,6,3,2,4,3,2,6,1,3,2 = 45
  • 45 / 15 = 3
  • Thrillville: 8,6,5,7,2,5,4,2,1,9,3,8,3,7,5,2,9,4,2,8 = 100
  • 100 / 20 = 5
  • 5 - 3 = 2

Therefore, on average, people visit Thrillville 2 more times per year than Funland.
