Statistics math ! need to get grade up! i have the answer i just need the steps on how to get there

The frequency refers to how many times a test scores within that particular range.

To find this answer, we must divide the number of scores we are interested in by the number of total scores, aka (n/500).

We are interested in the range of 70-89, and we notice there are 2 boxes included in this range: 70-79 and 80-89.

In the 70-79 range we see that there are 172 out of 500 scores.

In the 80-89 range we see that there are 105 out of 500 scores.

If you add these scores, you are given 277 out of 500 scores, aka (277/500), which gives us 0.554

You were on the right track with the answer you chose but you just forgot to include the 80-89 range. Hope this helps!
