Using a confidence interval when conducting a two-tail test for m , we do not reject H ₀ if the hypothesized value for m : 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 conducting a two-tailed test for a mean (m), if the hypothesized value for m falls between the lower confidence limit (LCL) and the upper confidence limit (UCL) of the confidence interval, we do not have sufficient evidence to reject the null hypothesis. This is because the confidence interval contains the range of values that are considered plausible for the population mean based on the sample data, and if the hypothesized value is within this range, it is considered consistent with the data.
