Two independent samples have the same sample number (n1 = n2 = 25) and the sample standard deviation are identical (s₁ = S₂ = 10). The sample information shows that the 95% Confidence Intervals of the two population means overlap by 1. Is there enough evidence to show the two-population means are different (a =5%)?
