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:

(i) Use a calculator with sample mean and sample standard deviation keys to calculate x₁, s₁, x₂, and s₂. (Round your answers to two decimal places.)

x₁	=
s₁	=
x₂	=
s₂	=

(ii) Assuming the variables x₁ and x₂ are independent, do the data indicate that the population mean time lost due to stressors is greater than the population mean time lost due to intimidators? Use a 5% level of significance. (Assume the population distributions of time lost due to intimidators and time lost due to stressors are each mound-shaped and symmetric.)
(a) What is the level of significance?

What is the value of the sample test statistic? (Test the difference μ₁ − μ₂. Do not use rounded values. Round your final answer to three decimal places.)
