X-4/3 <= 5
Multiply both sides by 3:
X-4 <= 15
Add 4 to both sides:
X <= 19
The answer is the third one.
1 SD away from mean is 68% of data.
2 SD away from mean is 95% of data.
3 SD away from mean is 99.7% of data.
1 SD away:
190+30=220
2 SD away:
220+30=250
This shows we are on the outer 5 percent of the normal distribution.
Since you said "more", that means we only look at the right side of your 5%, which is only 2.5%
answer is D, 2.5%
