World Military Expenditure The following chart shows total military and arms trade expenditure from 2011–2020 (t = 1 represents 2011).
†A bar graph titled "World military expenditure" has a horizontal t-axis labeled "Year since 2010" and a vertical axis labeled "$ (billions)". The bar graph has 10 bars. Each bar is associated with a label and an approximate value as listed below.
1: 1,800 billion dollars
2: 1,775 billion dollars
3: 1,750 billion dollars
4: 1,730 billion dollars
5: 1,760 billion dollars
6: 1,760 billion dollars
7: 1,850 billion dollars
8: 1,900 billion dollars
9: 1,950 billion dollars
10: 1,980 billion dollars
(a)
If you want to model the expenditure figures with a function of the form
f(t) = at2 + bt + c,
would you expect the coefficient a to be positive or negative? Why? HINT [See "Features of a Parabola" in this section.]
We would expect the coefficient to be positive because the curve is concave up.
We would expect the coefficient to be negative because the…

Q1. The table provided gives data on indexes of output per hour (X) and real compensation per hour (Y) for the business and nonfarm business sectors of the U.S. economy for 1960–2005. The base year of the indexes is 1992 = 100 and the indexes are seasonally adjusted.
a. Plot Y against X for the two sectors separately.
b. What is the economic theory behind the relationship between the two variables? Does the scattergram support the theory?
c. Estimate the OLS regression of Y on X.
Note: on the table ( 1. Output refers to real gross domestic product in the sector. 2. Wages and salaries of employees plus employers’ contributions for social insurance and private benefit plans. 3. Hourly compensation divided by the consumer price index for all urban consumers for recent quarters.)
Thank you!
