3. Suppose we measure a quantity y as a function of a parameter z. The measurement errors ony are denoted by ơ. Given 3 measurements. 11.0 1.10 0.08 2 2.0 4.40 0.20 3 3.0 8.80 0.20 we describe the data by the model, where α is an unknown parameter. a) Define χ2 and use it to determine the best estimate, a", of a. b) Find the value of x2 at the best estimate a. Did we choose a good model...
