The accompanying data give the prices (in dollars) for gold link chains at the Web site of a discount jeweler. The data include the length of the chain (in inches) and its width (in millimeters). All of the chains are 14-carat gold in a similar link style. Use the price as the response. Complete parts (a) through (f) below. Click the icon to view the gold chain data.

A. The residual plot has less of a pattern and exposes previously unknown outliers. B. There is no obvious pattern to the residuals. C. There is a clear linear pattern to the residuals. D. There is a clear nonlinear pattern to the residuals. (f) Summarize the fit of the improved model. The fit has R2 = 0.94 and s = $ 58.07 (Round to two decimal places as needed.)
