1. A study was made on the amount of converted sugar in a certain process at
various temperatures. The data were coded and recorded as follows:
Temperature, ¤
1.0
Converted Sugar, y
8.1
1.1
1.2
7.8
8.5
9.8
9.5

2.0
8.9
8.6
10.2
9.3
9.2
10.5
(a) Estimate the linear regression line.
(b) Estimate the mean amount of converted sugar produced when the coded
temperature is 1.75.
(c) Plot the residuals versus temperature. Make your own conclusion.
