1. Mathematica: Hubble

2. Enter the Hubble data
hubble = {{0.032, 170}, {0.034, 290}, {0.214, -130}, {0.263, -70},
{0.275, -185}, {0.275, -220}, {0.45, 200}, {0.50, 290},
{0.50, 270}, {0.63, 200}, {0.8, 300}, {0.9, -30},
{0.9, 650}, {0.9, 150 }, {0.9, 500}, {1, 920},
{1.1, 450}, {1.1, 500}, {1.4, 500}, {1.7, 960},
{2, 500}, {2, 850}, {2, 800}, {2, 1090}}

3. Make a ListPlot of the Hubble data

4. Click on the label button from the suggestions that arise

5. Result of adding labels

6. Use the LinearModelFit – linear here means that it is linear in the fit parameters

7. The ParameterTable option gets some of the statistical measures for the fit

8. Use Normal to extract the simple fit formula from all the associated statistical data. Then plot the fit function

9. Use Show to put the ListPlot of the data and the Plot of the fit formula together

10. We can get the equation displayed as well
