Answer:

4.88

Step-by-step explanation:

The actual mean is 4.88 to the nearest hundredth. She either approximated the sum of elements to 40 instead of 39 or she approximated the actual mean to the nearest whole number.

I think she gave an approximated average or a rounded average, but I am not sure.
