We can be confident that the population means differ for two conditions of an experiment when the confidence intervals for the two sample means

Question

Quizplus · Accepted Answer

If the confidence intervals for the two sample means do not overlap, it means that there is a significant difference between the two sample means at the given confidence level. Overlapping intervals indicate that there may not be a significant difference between the two population means. The size of the confidence interval and the standard deviations can provide additional information on the precision and variability of the estimate but are not sufficient to determine if there is a significant difference between the two means.
