z=</span></span>

z=</span></span>

<span><span>.
Using a z-table, we see that the area to the left of, or less than, this score is 0.8413. We want to know how many students scored more than this, so we subtract from 1:
1-0.8413=0.1587, which rounds to 16%.</span></span>
<span>If it's just like the last one, then 15 because in my head abc can equal 123 and def = 123 so 23 = 15. If that makes any sense lol</span>
