Answer: Positive.
Explanation:
Suppose there are two related goods, i.e, Good A and Good B.
Cross price elasticity of demand refers to the responsiveness of demand for Good A if there is a change in the price of its related good, i.e, Good B.
Now, we are talking about gasoline and public transportation, suppose if there is increase in the price of gasoline then it will be costlier for the people to drive their own cars, as a result demand for public transportation increases.
There is a positive relationship between the gasoline and public transportation.
Hence, cross-price elasticity of demand between gasoline and public transportation is Positive.
Answer:
- <em>As explained below, given that the score of the person is among the 0.03125 fraction of the best applicants, </em><u><em>he can count on getting one of the jobs.</em></u>
<em></em>
Explanation:
The hint is to use <em>Chebyshev’s Theorem.</em>
Chebyshev’s Theorem applies to any data set, even if it is not bell-shaped.
Chebyshev’s Theorem states that at least 1−1/k² of the data lie within k standard deviations of the mean.
For this sample you have:
- mean: 60
- standard deviation: 6
- score: 84
The number of standard deviations that 84 is from the mean is:
- k = (score - mean) / standar deviation
- k = (84 - 60) / 6 = 24 / 6 = 4
Thus, the score of the person is 4 standard deviations above the mean.
How good is that?
Chebyshev’s Theorem states that at least 1−1/k² of the data lie within k standard deviations of the mean. For k = 4, that is:
- 1 - 1/4² = 1 - 1/16 = 0.9375
- That means that half of 1 - 0.9375 are above k = 4: 0.03125
- Then, 1 - 0.03125 are below k = 4: 0.96875
Since there are 70 positions and 1,000 aplicants, 70/1,000 = 0.07. The compnay should select the best 0.07 of the applicants.
Given that the score of the person is among the 0.03125 upper fraction of the applicants, this person can count of geting one of the jobs.
Answer:
Agent Armstrong needs to be licensed and appointed in every state in which beneficiaries to whom he markets ABC MA plans are located.
Explanation:
In the given scenario XYZ Agency maintains a website marketing the MA plans with which it has contracts. So they are not in one location.
Clients from multiple states can subscribe to their services via website.
Agent Armstrong follows up with individuals who request more information about ABC MA plans via the website and tries to persuade them to enroll in ABC plans.
Since clients enroll in different locations there is a need for Armstrong to be licensed and appointed in every state in which beneficiaries to whom he markets ABC MA plans are located.
This will satisfy the varying compliance rules that each state of operation may have. Thereby providing seamless service delivery to customers of XYZ agency.
