Question

In large corporations, an "intimidator" is an employee who tries to stop communication, sometimes sabotages others, and, above all, likes to listen to him or herself talk. Let x₁ be a random variable representing productive hours per week lost by peer employees of an intimidator.

x₁:

A "stressor" is an employee with a hot temper that leads to unproductive tantrums in corporate society. Let x₂ be a random variable representing productive hours per week lost by peer employees of a stressor.

x₂:

x1: 3.8571 s1: 2.1157 | x2: 5.625 s2: 2.8754 | Level of Significance: 0.05 | H₀: ?₁ = ?₂; H₁: ?₁ < ?₂
