study (reported in Science, 1982), 287 normal children ranging from 2 to 16 years old were instructed
to hold a 65-gram weight in the palm of their outstretched hand for a brief but unspecified time
The peak EEG frequency (measured in hertz) was then recorded for each child. The children we
grouped according to age, and the average peak frequency for each age group was recorded. The
data appear in the accompanying table.

a. Construct a scattergram for the data.
b. Find the least squares prediction equation.
c. Graph the least squares line on the scattergram.
d. Use the least squares prediction equation to predict the average peak EEG frequency y of x =
7-year-old normal children. [Note: We will find a measure of the reliability of this prediction in
Section 3.9.]
