How do I do this I don’t understand

9514 1404 393

  a) 74.5%

  b) 84.3%

Step-by-step explanation:

a) If you were to refer to the glossary, as the problem statement suggests, it would tell you how to do this. Add up the scores and divide by the number of them.

Here, the 8 given scores have a total of 596%, so their mean is ...

  596%/8 = 74.5%

Brandee might argue that this score does not really represent her abilities, because her abilities were not demonstrated properly on one of the tests.

__

b) Replacing the 0 score with 78% brings the total to 674%, so the new mean is ...

  674%/8 = 84.3%

_____

Additional comment
