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 .
i would say D C and maybe a but C makes the most since hope this helps
Answer:
The correct answer is letter "A": Heckscher-Ohlin.
Explanation:
Named after Swedish economists Eli Heckscher (1879-1952) and Bertil Ohlin (1899-1979), the Heckscher–Ohlin theory states that countries should focus their efforts on producing and exporting those goods they are good at manufacturing and they should import the goods they struggle in making. The concept is based on both the productivity and non-productivity of nations and their best bequests.
Answer:
a) 12.87%
b) 11.03%
Explanation:
EBIT with no debt = $111,000
net income = $111,000 x (1 - 22%) = $86,580
total value of the firm with no debt = $86,580 / 12% = $721,500
value of the firm after debt is taken = $721,500 + ($165,000 x 22%) = $757,800
debt to equity ratio after debt is taken = $165,000 / ($757,800 - $165,000) = 27.834%
new cost of equity (Re) = 12% + [(12% - 8%) x 27.834% x (1 - 22%)] = 12.87%
WACC = (0.72166 x 12.87%) + (0.27834 x 8% x 0.78) = 9.288% + 1.737% = 11.025$ = 11.03%
