WebOct 27, 2024 · The confidence intervals for the difference in means provide a range of likely values for (μ 1-μ 2). It is important to note that all values in the confidence interval are equally likely estimates of the true value of (μ 1-μ 2). If there is no difference between the population means, then the difference will be zero (i.e., (μ 1-μ 2).= 0).
