You’re a human factors engineer examining the reaction time of pilots to two different instrument panel layouts (A, B). You asked eight pilots to undergo a simulated disruption scenario, and you recorded their reaction time (in seconds) to resolve the scenario using layout A. You asked the same of 11 pilots for layout B. Sample statistics are below. Assume the variances are sufficiently different. Use the critical value approach considering 0.05 significance.
