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%
Answer:
The Federal government relies the most on income tax.
Step-by-step explanation:
Ok so
250 left for student desks
250≥8n
n=number of desks
solve
divide both sides by 8
31.25≥n
round down since we cannot have a decimal desk
31 desks
but, the teacher has 1 desk also so add 1
31+1=32
Hopefully this can help you
