In a wildlife preserve, a random sample of the population of 150 raccoons was caught and weighted. The results, given in pounds were 17, 19, 20, 21, 23, 27, 28, 28, 28, and 32. Jean made the qualitative statement, " the average weight of raccoons is 25 pounds". Is her statement reasonable. Explain

Respuesta :

     First you add all of the results together for a sum of 243. Then, you divide that sum, 243 by 10, the number of results in total. That means the average weight of 10 random raccoons out of 150 raccoons in that wildlife preserve, is 24.3 pounds. Her statement is not reasonable because Jean stated the average weight of ALL raccoons is 25 pounds.

I hope this helps you out!
