Question

Need Help Please I'm Out Of Time ;(

The mean age of Lincoln's tee-ball team is 5. Suppose one of his 7-year-old teammates quits the team, but a 6-year-old joins the team. Is the mean age of Lincoln's team still 5? Explain your reasoning.

Answer 1

No

Explanation:

Mean age = (the sum of the ages)/number of people

So, if 7 is replaced with 6 ,the sum will be different so the mean age will not be the same
