8.1 Consider the data from Hubble’s experiment in Table 8.1.

(a) Determine the best-fit values of the fit to a linear model for .m; log v/ assuming that the dependent variables have a common value for the error.

(b) Using the best-fit model determined above, estimate the error from the data and the best-fit model, and then estimate the errors in the parameters a and

b, and the correlation coefficient between a and b.

(c) Calculate the minimum 2 of the linear fit, using the common error as estimated in part (a).
