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 .
Answer: $6,000,000
Explanation:
Hi, to answer this question we simply have to multiply the total market capital of the company (20,000,000) by the percentage under preferred stock (30%) in decimal form.
Mathematically speaking:
20,000,000 x (30/100) = $6,000,000
Feel free to ask for more if needed or if you did not understand something.
Sales: $914,000
Variable Costs: $498,130
Operating Income: $196,000
Contribution Margin Ratio = ?
Formula:
Contribution Margin Ratio = (Sales – Variable Costs) / Sales
Solution:
Contribution Margin Ratio = ( $914,000 - $498,130) /
$914,000
Contribution Margin Ratio = 45.5% (Answer)

Professor Thompson has decided to wait until the class period ends, take both tests and compare their answers. After that she will decide what to do about the situation. Professor Thompson has thus entered the first step, which is to gather information. She doesn't want to jump to conclusions without gathering all the facts, so she is going to acquire as much info as she can about the situation before continuing. All these points add to the fact that Professor Thompson is entering the first step towards making the best ethical decision.
