You want to test the following hypotheses. There are three categories: x, y and z. H0: px = .20, py = .40, and pz = .40 HA: The population proportions are not px = .20, py = .40, and pz = .40 A sample size of 200 resulted in 20 observations in category x, 120 in category y and 60 in category z. Use α = .01 and test to see whether the proportions are as stated in H0. Use the p-value approach. How many degrees of freedom are there?
