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 .
Waiting is a bad idea because you could lose good opportunities in the time you wait. Choosing the same career as someone you admire might not be what you would best enjoy or succeed in, and the job that earns you the most money isn't necessarily the most enjoyable. The answer is A :)
It must be debatable. Hope this helps
Internal growth rate is calculated by dividing retained earnings by total assets.
Retained earnings is calculated by subtracting dividends from net income
So: Retained earnings would be 12,493 - (12,493 X .4)
Then to find internal growth rate take your retained earning from above and divide by total assets (the total on the balance sheet : 106,900).
