Follow-up Question

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?
