Answer: The correct answer is "a. decisions under risk.".
Explanation: The decision situations wherein the decision-maker chooses to consider several possible outcomes and the probabilities of their occurrence can be stated are called <u>decisions under risk.</u>
Decision-making under risk is one of the three possible decision-making scenarios based on the available information, this scenario presents an intermediate situation between decision-making under certainty or under uncertainty: each alternative, strategy or course of action has several possible consequences, but the person in charge of making the decision knows the probability of each of them.
Answer:
c. 108.3
Explanation:
Calculation to determine what The value of the CPI in 2004 was:
Using this formula
Consumer Price Index (CPI) 2004 = (2004 Basket cost / Base year basket cost) x 100
Let plug in the formula
Consumer Price Index (CPI) 2004 = (650 / 600) x 100
Consumer Price Index (CPI) 2004 = 108.3
Therefore The value of the CPI in 2004 was:108.3
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 .
