Question

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:

Temp.	Conv. sugar
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) Estimate the linear regression line.

(b) Estimate the mean amount of converted sugar produced when coded temperature is 1.75.

(c) Estimate the conditional standard deviation of converted sugar on temperature.

(d) Estimate the correlation coefficient of converted sugar on temperature.

(e) Determine and plot data, the regression line and the 90% confidence interval of the above regression equation in the same plot.
