The data table found below contains the listed prices and
weights of the diamonds in
20 rings offered for sale in a newspaper in a foreign city. The
prices are in local dollars with the weights in carats.
​(b) Estimate the linear equation using least squares. Interpret
the fitted intercept and slope. Be sure to include their units.
Note if either estimate represents a large extrapolation and is
consequently not reliable.
Complete the equation for the fitted line below.

​(Round to two decimal places as​ needed.)
(c) Interpret the summary values r2 and se associated with the
fitted equation. Attach units to these summary statistics as
appropriate.
