Question

Gina is a tour boat operator and she wants to know the mean age of all the people in her tour group.

She randomly selects 8 people in the group and asks them for their ages. Their responses are 19, 27, 25, 21, 44, 22, 45, and 34.

What is the best estimate of the mean age of all the people in the tour group?



Round to the nearest whole number.

Answer 1

30 years

This is the correct answer! I just took the test! Good luck!

Answer 2

mean means average, so add all the ages together and divide by the number of people asked:

19 + 27 + 25 + 21 + 44 + 22 + 45 + 34 = 237

237 / 8 = 29.625 = 30 years
