Brainly if correct

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

Respuesta :

Answer:

    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.

Step-by-step explanation:

hope this helps :)
No, because the average weight of the raccoons is 24.3 pounds.

Step 1) 17+19+20+21+23+27+28+28+28+32=243

Step 2)
243 divided by 10 = 24.3pounds
