Using a confidence interval when conducting a two-tail test for $\mu$,we do not reject H₀ if the hypothesized value for$\mu$: A) is to the left of the lower confidence limit (LCL). B) is to the right of the upper confidence limit (UCL). C) falls between the LCL and UCL. D) falls in the rejection region.

When using a confidence interval for a two-tail test, we can fail to reject the null hypothesis if the hypothesized value falls within the range of the confidence interval, which is between the lower and upper confidence limits. Therefore, if the hypothesized value falls between the LCL and UCL, we do not reject the null hypothesis.
