Answer to Question 1

D

Answer to Question 2

A test of the hypothesis that data are generated by a fully specified probability distribution is a technique that is often used by market researchers to determine if products are equally preferred by potential customers or to check if the market shares for several brands of a product have changed over a given period of time. To test the hypothesis that data are generated by some distribution, such as the binomial, the Poisson, or the normal, without assuming the parameters of that distribution to be known is another important use of Goodness-of-Fit-tests.
