31) ($6 * 2) + $6.25 + $4.25 + $20 = $42.50
32) $50 - $8.25 - $4.25 -$4.25 - $20 = $13.25
33) 6 * 15.99 = 95.94 | $100 - $95.94 = $4.06
34) $10.50 * 8 = 84 | $100 - $84 = $16
Hope this helps! ^^

Answer:
Population A
Step-by-step explanation:
Think about. If population A already known for normally distribution AND you take large samples. The rest would still be distributed, Which keeps population A a Normal Distribution.

x=25,y=15 Not to sure abt this answer but I think I got it
