Explanation:
When a particular quantity of output is produced, an identical quantity of income is generated because the output belongs to someone. Thus we have the identity that output equals income (where an identity is an equation that is always true regardless of the values of any variables).
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 with Explanation:
Following are some types of account investments that are better for emergency funds and the return on these investment varies depending upon the risk born by the investors:
- Current Account Investments
- Commodity Investments
- Mutual Funds
If the inflation rate is below the return paid on the current account then it could be a better investment option as the money doesn't loose its value over time.
If the inflation rate is higher than the return paid on the current account then it is better to invest in commodities like gold, petroleum products, etc, that are often termed as speculative investments.
If the investor is risk seeking person, then it is better to invest in mutual funds as the return on such investments is higher because of the higher risk that the investor bears.
