In an experiment, researchers wanted to know whether changing the level of lighting in a factory would have an effect on the productivity of employees
In order to address this question, employees were randomly assigned to three separate identical work areas, but the lighting was set at a different level in each of the work areas. Then, employees in all three work groups began to operate machinery that produced small electrical components. The number of components produced by each group was carefully tallied at the end of each 8-hour shift. In this example, the hypothesis is the ________. a) presence or absence of the researchers will affect productivity
b) number of components produced will not change because of lighting
c) level of lighting will affect employee productivity
d) employees chosen to participate in the research will affect productivity
c
