When evaluating c 2obt , the critical region for rejection of H 0 _________.
A) lies under both tails of the distribution
B) lies under the right hand tail of the distribution
C) lies under the left hand tail of the distribution
D) lies in the middle of the distribution

When evaluating c 2obt, the critical region for rejection of H0 lies under the right-hand tail of the distribution. This is because the chi-square test is typically used to determine if a sample variance is significantly different from a hypothesized population variance, and the alternative hypothesis is usually that the sample variance is greater than the hypothesized population variance. Therefore, the critical region for rejection is in the upper tail of the distribution.
