The closest to the minimum number of consumers needed to obtain the estimate with the desired precision is (b) 271
Explanation:
When the prior estimate of population proportion is not given , then the formula to find the sample size is given by :-
where E = Margin of error.
z* = Critical z-value.
As per given , we have
E = 5%=0.05
Confidence level = 90%
The critical value of z at 90% is 1.645 (By z-table)
Put all values in the formula , we get
n=0.25(1.645/0.05)²
n=0.25(32.9)²
n=270.6025≈271
Thus, the minimum sample size needed = 271
Hence , the correct answer is 271 .
Your answer would be B. The price will go up because supply is low.

Answer:
FV= $12,818.4
Explanation:
Giving the following information:
You are hoping to buy a new boat 3 years from now, and you plan to save $4,200 per year, beginning one year from today. You will deposit your savings in an account that pays 5.2% interest.
To calculate the future value we need to use the following formula:
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
FV= {4,200*[(1.052^2)-1]}/0.052 + 4,200= $12,818.4
