Solved: The grams of solids removed from a material (y) is
Chapter , Problem 105SE(choose chapter or problem)
The grams of solids removed from a material \((y)\) is thought to be related to the drying time. Ten observations obtained from an experimental study follow:
(a) Construct a scatter diagram for these data.
(b) Fit a simple linear regression model.
(c) Test for significance of regression.
(d) Based on these data, what is your estimate of the mean grams of solids removed at 4.25 hours? Find a \(95 \%\) confidence interval on the mean.
(e) Analyze the residuals and comment on model adequacy.
