Exercise 11.17: 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, x
Converted Sugar, y
1.0
8.1
1.1
7.8
1.2
8.5
1.3
9.8
1.4
9.5
1.5
8.9
1.6
8.6
1.7
10.2
1.8
9.3
1.9
9.2
2.0
10.5
(a) evaluate s2;
(b) construct a 95% confidence interval for β0;
(c) construct a 95% confidence interval for β1.
Using the value of s2found in Exercise 11.17(a), construct a 95% confidence interval for the amount of converted sugar corresponding to x = 1.6.
