<span>"What do you think is the most important problem facing this country today?"
16% of the respondents answered
"crime and violence."
The margin of sampling error was plus or minus 3%
Following the convention that the margin of error is based on a 95% confidence interval, find a 95% confidence interval for the percentage of the population that would respond "crime and violence" to the question asked by the pollsters.
hmmm, im thinking this looks familiar to me, but ill have to see whats wrong about it first
using .16 as p^ and therefore 1-p^ = q^ = .84</span>

Answer:
10. 48 degrees 11. Use explanation below. 12. 25 degrees 13.Use explanation below. 14. 63 degrees 15. Use explanation below. 16. 130.5 17. A. 48 degrees B. 90 degrees and C. 42 degrees 18. Explain
Step-by-step explanation:
10. All triangles angles add up to 180 degrees, so 100+32=132 and 180-132=48
11. Use the explanation above.
12. Using the rule above 88+57=145 and 180-145= 25
13. Use explanation above.
14. Add the two answers from 10 and 12. 48+25= 63
15. Use explanation above.
16. Using the triangle 180 degrees rule add 90 degrees (Angle a is a right angle which is always 90 degrees) to 40.5 degrees. 40.5 + 90= 130.5
17. You have angle A (48) angle B is a right angle aka 90 degrees and using the rule 90+ 48= 138 and 180-138= 42
18. I think you can explain it now (I hope)
