Inference for Simple Linear Regression in MINITABTM

Chapter 9, Printout 1

Note: The data set for this example is identical to that for Printout 1 of Chapter 4. The procedures are similar to those in Sections 1 and 2 of the "Fitting a Line by Least Squares" example, but additional steps are shown for inferences in simple linear regression.

Section 1: Making a Fitted Line Plot

  1. Launch MINITAB.

  2. Enter the data.

  3. Generate the fitted line plot with confidence curves and prediction limits.

    MINITAB displays a fitted line plot of Density vs. Pressure.

Section 2: Obtaining the Fitted Linear Equation and Additional Numerical Summaries

  1. Display summary information for the fitted line.

    MINITAB displays summary information, including the regression equation, a table of fits and residuals, and a predicted value for x=5000.
