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:
If you considered that outstanding shares are equal that total shares, then: market capitalization is $1.085 billions; market value added is $477.5 millions and the market-ti-book ratio is 1.78.
Explanation:
To get these numbers we calculate as follow: market capitalization = number of shares multiply by the price per share (75$ x 14.5 million); marked value added = market capitalization - (total assets - liabilities) [1.085 Bn - (1 Bn - 390 m)] ; and market-to-book ratio = market capitalization / book value (1.085bn/610m)
Monopolistically competitive firms (A) cannot influence the market price by virtue of their size alone while monopolies and oligopolies can.
<h3>
What is a monopoly?</h3>
- A monopoly occurs when there is a single seller in the market.
- The monopoly case is considered the polar opposite of perfect competition in conventional economic theory.
- The demand curve facing the monopolist is, by definition, the industry demand curve, which is downward sloping.
<h3>What is
oligopoly?</h3>
- Oligopolistic markets are characterized by a small number of suppliers.
- They can be found in all nations and in a wide range of industries.
- Some oligopoly markets are very competitive, whereas others are substantially less so, or appear to be.
Monopolistically competitive enterprises, unlike monopolies and oligopolies, cannot influence market prices only through their size.
Therefore, monopolistically competitive firms (A) cannot influence the market price by virtue of their size alone while monopolies and oligopolies can.
