A chi-square test of independence yields chi-square = 9.21 with 4 degrees of freedom.
Which best describes the p-value?
- Acheck_circle
P(chi-square >= 9.21 | df=4)
- B
P(chi-square <= 9.21 | df=4)
- C
P(chi-square = 9.21 | df=4)
- D
P(chi-square > 9.21 | df=5)
Explanation
The p-value for a chi-square test is the probability of observing a chi-square statistic at least as extreme (i.e., as large or larger) as the observed value, under the null hypothesis.
