Expert Solution & Answer
Explanation of Solution
Trend analysis is an important component or technique of Time Series, which uses past data to predict the future. It indicates the change in a variable over a given time period. It may be stationary, positive, or negative.
A positive trend is one in which a rise in one set of data results in an increase in the other set. And a negative trend is one in which a rise in one set of data results in a decrease in the other set. On the other hand, if one set of data rises but the other does not appear to rise or fall, a trend is not there.
Graph:
The graph representing the stationary trend is:
The graph representing a positive or upward trend is:
The graph representing a negative or downward trend is:

- The amount of carbon dioxide in the atmosphere has been increasing over the past century as a result of the combustion of fossil fuels (coal, oil, and natural gas). Carbon dioxide is a green- house gas that plays a significant role in climate. The increase in carbon dioxide is correlated with changes in climate that have climate scientists concerned. The graph shown here illustrates the increase in atmospheric carbon dioxide from 1860 to the present. Study the graph and answer the questions that follow. 410 400 390 380 370+ 360+ 350 - 340 + 330+ 320+ 310+ 300 290 1860 1880 1900 1920 1940 1960 1980 2000 2020 Year A Atmospheric carbon dioxide concentration from 1850 to present.
