Economists at USF Are Researching the Problem of Absenteeism at U.S

question 39

Multiple Choice

Economists at USF are researching the problem of absenteeism at U.S. firms. A random sample of 100 U.S. organizations was selected to participate in a 1-year study. As part of the study, the
Economists had collected data on the following two variables for each company: shiftwork
Available (Yes or No) , and union-management relationship (Good or Poor) . As part of their
Analyses, the economists wanted to determine whether or not a company makes shiftwork
Available depends on the relationship between union and management. The collected data are
Shown below: Relation
$\begin{array} { l c c c } \text { Shiftwork } & \text { Good } & \text { Bad } & \text { Total } \\ \text { No } & 11 & 22 & 33 \\ \text { Yes } & 25 & 42 & 67 \\ \text { Total } & 36 & 64 & 100 \end{array}$
In order to determine whether the shiftwork responses depend on the relationship responses, a two-way chi-square analysis should be conducted. Calculate the value of the test statistic for the desired analysis.

• A) \(\chi ^ { 2 } = 11.88\)
• B) \(\chi ^ { 2 } = 0.07\)
• C) \(\chi ^ { 2 } = 0.70\)
• D) \(\chi ^ { 2 } = 0.15\)

Definitions:

Sensory Adaptation

The process by which sensory receptors become less sensitive to constant or unchanging stimuli.

Stimulus Energies

The physical or environmental energies that an organism can detect and respond to, such as light, sound, and temperature.

Sensory Receptors

Specialized cells or nerve endings that respond to changes in the environment and transmit signals to the nervous system.

Sensation

The process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.
