An example of the statistical treatment of an urban spot speed study is given
below. Table 10.2 shows a set of 130 observations of spot speeds made by
timing vehicles through a "trap" of 88 feet. In this example, the stopwatch
data are grouped into 0.2 sec classes (a 1/5 sec stopwatch was used to obtain
the data). The first column of the table shows the midpoint of each group. The
second column shows the frequency of the observations. The cumulative percent
shown in the third column is obtained by dividing each cumulative frequency
(for example, 8 vehicles took 5 sec or longer to pass through the trap) by
the total number of observations and multiplying by 100 (8 x 100/130 = 6.2
percent). The next two columns are computed to develop the average and variance
of the space distribution. The sixth column indicates the speed of each
time class and the last two columns are used to obtain the average speed
and variance of the time distribution.

We want to predict the selling price of a house in Newburg Park, Florida, based on the distance the house lies from the beach. Suppose that we're given the data
in the table below. These data detail the distance from the beach (x, in miles) and the selling price (v, in thousands of dollars) for each of a sample of sixteen
homes sold in Newburg Park in the past year. The data are plotted in the scatter plot in Figure 1. Also given is the product of the distance from the beach and
the house price for each of the sixteen houses. (These products, written in the column labelled "xy", may aid in calculations.)
