In a hypothesis test for the population variance,the hypotheses are H₀: $\sigma$² = 100 vs.H₁: $\sigma$² $\neq$ 100.If the sample size is 15 and the test is being carried out at the 10% level of significance,the rejection region is: A) $\chi$² 23.685. B) $\chi$² 21.064. C) $\chi$² 22.307. D) $\chi$²
