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
