The purity of oxygen produced by a fractional distillation process is thought to be related to the percentage of hydrocarbons in the main condensor of the processing unit. Twenty samples are shown below. a. Fit a simple linear regression model to the data.
- Test the hypothesis H0: β1 = 0.
- Calculate R2.
- Find a 95% CI on the slope.
- Find a 95% CI on the mean purity when the hydrocarbon percentage is 1.00.
