U.S. Nitrogen Oxide EmissionsData was collected on nitrogen oxide emissions in the United States from 1970 to 2000 in 5 year inter-
vals. The data was put into ordered pairs with the first number being the year, the second number
beingnitrogen oxide emissions in millions of metric tones, and can be seen below. To plot these data
points, we use the function ListPlot[data] and the outcome was a graph of the emissions as a function
of the year. We named that plot p1.

In[4]:= p2 = Plot@A@tD, 8t, 1970, 20002 joins the data by quadratic cirlces. The estimated
total emissions of nitrogen oxide for InterpolationOrder->1 were 772.75, and for InterpolationOrder->2, it
was 774.333. These steps can be followed below.
