One manufacturer has developed a quantitative index of
the​ "sweetness" of orange juice.​ (The higher
the​ index, the sweeter the​ juice). Is there a
relationship between the sweetness index and a chemical measure
such as the amount of​ water-soluble pectin​ (parts
per​ million) in the orange​ juice? Data collected on
these two variables for 24 production runs at a juice manufacturing
plant are shown in the accompanying table. Suppose a manufacturer
wants to use simple linear regression to predict the
sweetness​ (y) from the amount of pectin​ (x).
a. Find the least squares line for the data.
