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 .
the answer to this question is 4.70%
Answer: price leadership
Explanation: Price leadership is a circumstance where one business, typically the dominant one in its market, sets prices that its rivals follow closely.
This business is typically the one with the minimum cost of production, thus being able to outperform the prices charged by any rival who tries to set their prices below the price range of the market leader.
Rivals could increase prices than the cost leader, but this would likely lead to lower share of the market unless rivals were able to distinguish their goods adequately.
Hence from the above we can conclude that the given case depicts price leadership strategy.
The return on investment for this division is (B) 20%.
<h3>
What is the return on investment (ROI)?</h3>
- Return on investment (ROI) or return on costs (ROC) is a ratio of net income to investment over time (costs resulting from an investment of some resources at a point in time).
- A high ROI indicates that the benefits of the investment outweigh the costs.
- ROI is used as a performance indicator to evaluate the efficiency of an investment or to compare the efficiencies of several investments.
- It is one method of connecting profits to capital invested in economic terms.
<h3>To find the return on investment for this division:</h3>
= income/average invested assets
= $40,000/$200,000
= return on investment
= 20%
Therefore, the return on investment for this division is (B) 20%.
