A sample of 300 customers was taken to see if the market shares had changed. In the sample, 100 of the people were under 30 years old, 150 people were between 30 and 50 years old, and 50 people were over 50 years old. What are the degrees of freedom associated with this hypothesis test? df = 1 df = 6 df = 3 df = 2
