Question 5 (5 points) Suppose we have a multinomial population with four categories: A, B, C, and D. The null hypothesis is that the proportion of items is the same in every category. The null hypothesis is Ha: pi =.p3 =pc =po= .25 A sample of size 300 yielded the following results. A:85 B:95 C:50 D:70 Use a = .05 to determine whether He should be rejected. What is the p-value? Expected equencies: (1 point) Actual frequencies: (0.5 point) 9* (1.5 points) degrees of freedom: I: - 1 = (0.5 point) 2 2 Using the 7C table with riff: 'X = ............. shows the p-value is ........ than ........... (0.5 point)
