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: Yes
Explanation: In the above case, a quasi-contract was formed. This is when a bilateral contract is not in place but one party will enjoy the benefit of the activities of the other party and may be enriched by it.
A bilateral agreement is the exchange of a promise for another and in this case would have been, the promise that Dozier would pay for Paschall’s work. This was not established, however, Dozier will benefit from Paschall’s work unduly if he does not pay for the improvements. The law holds that he has to pay for Paschall’s work to prevent being unjustly enriched.
That would be John D. Rockefeller who gained control over the oil market by buying up small companies and sell oil at a significantly lower price to force his competitors to sell to him and them when he had majority control over the oil market he them just muscled the remaining out of business and then jack up the price on his oil to rake in huge profits. <span />
False.... The amount of money taken out of a check for taxes depends on how much you're getting paid.
