You are trying to determine if a certain dice is fair (has a uniform distribution). You roll the dice 42 times and record the outcomes in the table below. Find the test statistic, χ20, for the chi-square goodness-of-fit test.
χ20=∑k(O−E)2E



Outcome 1 2 3 4 5 6
Expected 7 7 7 7 7 7
Observed 8 9 5 10 5 5

Select the correct answer below:


χ20≈0.449

χ20≈8.315

χ20≈3.714

χ20≈0.204

χ20≈1.429

χ20≈3.780
