Question

Mr. Zuro finds the mean height of all 15 students in his statistics class to be 67.0 inches. Just as Mr. Zuro finishes explaining how to get the mean, Danielle walks in late. Danielle is 63.8 inches tall. What is the mean height of the 16 students in the class?

Answer 1

Answer: 66.8

Step-by-step explanation:

Let the mean height of 16 students in the class = X

Therefore,

$\frac{15*67+63.8}{16} =X$

$X=\frac{334}{5}$

X = 66.8
