You can use a scatterplot to estimate a value between two known values. Estimate the world production of oil when the United States produced 12% of the world's oil.
Draw a scatterplot.
Find 12% on the vertical axis. More horizontally to the line of points. Estiamte where the new point would fit in the pattern. Then move down to the horizontal axis.
Oil Production 1960-2000 (billion barrels)
World Oil production: 45.9, 52.8, 59.9, 68.3, 72.5
U.S. Percent of world Oil Production: 21, 16, 13, 9, 7

Step 1
Scatterplot World Oil
Production is on thehorizontal axis and U.S. Percent of World Oil Production is on the vertical axis. The World Oil Production ranges from 7 to 21, thus an appropriate scale for the horizontal axis is from 0 to 22. The U.S.
Percent of World Oil Production ranges from 45.9 to 72.5, thus an appropriate scale for the vertical axis is from 30 to 80.

Step 2
We draw a horizontal line at 12% until we arrive at the location where we expect the new point to fit in the pattern. Next, we draw a vertical line through this expected new point. We note then note that this vertical line intersects the horizontal axis at approximately 62 and thus the estimated world production of oil when the United States produced 12% of the world’s oil is expect to be 62 billion barrels. Result: 62 billion barrels.

When σ is unknown and the sample size is \(\displaystyle{n}\geq{30}\), there are tow methods for computing confidence intervals for μμ. Method 1: Use the Student's t distribution with d.f. = n - 1. This is the method used in the text. It is widely employed in statistical studies. Also, most statistical software packages use this method. Method 2: When \(\displaystyle{n}\geq{30}\), use the sample standard deviation s as an estimate for σσ, and then use the standard normal distribution. This method is based on the fact that for large samples, s is a fairly good approximation for σσ. Also, for large n, the critical values for the Student's t distribution approach those of the standard normal distribution. Consider a random sample of size n = 31, with sample mean x¯=45.2 and sample standard deviation s = 5.3. (c) Compare intervals for the two methods. Would you say that confidence intervals using a Student's t distribution are more conservative in the sense that they tend to be longer than intervals based on the standard normal distribution?

The table shows the populations P (in millions) of the United States from 1960 to 2000. Year 1960 1970 1980 1990 2000 Popupation, P 181 205 228 250 282
(a) Use the 1960 and 1970 data to find an exponential model P1 for the data. Let t=0 represent 1960. (c) Use a graphing utility to plot the data and graph models P1 and P2 in the same viewing window. Compare the actual data with the predictions. Which model better fits the data? (d) Estimate when the population will be 320 million.
