Extracted text: Suppose that a response can fall into one of k = 3 categories with probabilities P = 0.4, p, = 0.3, and p, = 0.3, and n= 300 responses produce these category count: Category Observed Count 1 2 3 125 80 95 Do the data provide sufficient evidence to indicate that the cell probabilities are different from those specified for the three categories? Use a = 0.05 H: Category Observed Count (O) 1 3 125 80 95 Expected Count (E,) Test Statistic : Decision Rule: Conclusion: p-value :
