Answer: Option (a) is correct.
Explanation:
Correct Option: Panel data.
Panel data is a combination of cross sectional data and time series data. Panel data is mostly used for the regression analysis. In this type of data, one can observe multiple instances or scenarios at more than one time frame.
The information provided by this type of data can be categorized into parts:
(i) Cross-sectional Information
(ii) Time series Information
The net effect of these changes in the expenditure if the marginal propensity to withdraw is 20 percent is that the consumer spending will rice.
<h3>How to illustrate the information?</h3>
In Keynesian macroeconomic hypothesis, it illustrates the impact of the monetary improvement spending.
If the government wanted to get the same impact through buying goods and services, the thing to do to increase the spending on goods and service is to reduce taxes and increase its expenditure.
The impacts that this might this decision have on the economy is that it will enhance globalization and and increase in the standard of living.

There is only one firm that dictates the price and supply levels of goods and services.
Answer:
![[tex]Total benefit = b(q) = 20q – 2q^{2} Total cost is c(q) = 4 + 2q^{2} , Marginal benefit = mb(q) = 20 – 4q Marginal Cost = mc(q) = 4q.](https://tex.z-dn.net/?f=%5Btex%5DTotal%20benefit%20%3D%20b%28q%29%20%3D%2020q%20%E2%80%93%202q%5E%7B2%7D%20%20%0ATotal%20cost%20is%20c%28q%29%20%3D%204%20%2B%202q%5E%7B2%7D%20%2C%20%20%0AMarginal%20benefit%20%3D%20mb%28q%29%20%3D%2020%20%E2%80%93%204q%20%20%0AMarginal%20Cost%20%3D%20mc%28q%29%20%3D%204q.)
a. 
b. When q = 2
Marginal Benefit = 20 – 4q
= 20 - 4(2)
= 20 – 8
= 12 When q = 10
Marginal benefit = 20 – 4q
= 20 – 4(10)
= 20 – 40
= -20[/tex]
c. Total Benefits are maximised when MB=0
Therefore, q=5 maximizes total benefits.
d. Total cost is given by 
When q=2,
When q= 10
e. 
f. Total cost is minimized at Q=0. At any other level Total cost is increasing for every value of Q.
g. Net benefits are maximized when 
So, q=2.5 maximizes net benefits.
