There are 8 students on the school chess team. They need to raise at least $760 for a field trip. Their advisor says they still
need to raise 85% of the funds, and she wants each of them to raise an equal share of the money still needed.
Diego wrote and solved the inequality 8m + 0.85(760)> to find-
-
the least amount of money, m, each student on the chess team still needs to raise. He says the solution is m > $14.25
-
Describe and correct Diego’s error.

Answer: 554
Step-by-step explanation:
If prior population proportion is known, then the formula to find the sample size is given by :-
As per given description, we have
p= 0.1
E=0.025
Critical z-value for 95% confidence :
Then,
Hence, the minimum sample size required = 554.
