Answer:
The correct answer is:
$4 (D.)
Explanation:
From the question, we are told that:
the price of halvah (MUH)= $12
the price of pomegranates (MUP)= ????
Next, we are also told that the optimal consumption ratio of MUH to MUP = 3
This means that the Mauginal Utility of halvah (H) to the marginal utility of pomegranates (P) = 3
MUH/MUP = 3
12/MUP = 3
MUP =
MUP = $4
Answer:
And we can find this probability using the normal standard distribution table or excel and we got:
Explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the expected return, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the normal standard distribution table or excel and we got:
