A open education means what you share and customize
21.19%
First you need to find the z-score with
X- Mean
----------- = Zscore
Standard
Deviation
Then use your z table (should be on your formula sheet if not look one up)
to find your proportion (in this problem it would be .2119) and convert it to a percent.
So plug everything in
6.64-7.2
------------ = Z-Score
.7
Z-Score= 0.8
The table showed our proportion to be .2119
therefore your percent is 21.19%

Thats all I know sorry
I think the answer is yes you can because they are both different things.
What I mean by that is that the United Stated as .151% of its people with hearing problems, and .093% with vision problems. So really adding them together just mixes it saying that .244% of people in the united states have either a vision or a hearing problem.
It doesn’t make it any more or any less people by adding them together. Therefore it’s not any more or any less probable to pick one or the other.
Hopes this helps.
