Textbook Question
Chapter 4, Problem 44E
A plant distills liquid air to produce oxygen, nitrogen, and argon. The percentage of impurity in the oxygen is thought to be linearly related to the amount of impurities in the air as measured by the “pollution count” in parts per million (ppm). A sample of plant operating data is shown below:
- (a) Fit a linear regression model to the data.
- (b) Test for significance of regression.
- (c) Find a 95% confidence interval on β1.
