Answer 1

Mean is 87.5.

Mode is 90.

Explanation:

Part A:

Mean means the average.

So let's start adding up

70+70+80+80+80+80+90+90+90+90+90+90+100+100+100+100=1400

There are 16 test scores.

So divide 1400 by 16 to get the average.

1400/16 = 87.5

The mean is 87.5.

Part B:

Mode means the number that repeats the most. That's 90. 90 is the mode.
