question #9
the frequency polygon below represents the ages of workers at a local construction company.
which answer choice best explains the downward trend in the age of the workers and the number of workers?
construction jobs involve mostly supervising. workers tend to be older and more experienced.
construction jobs are physically demanding. workers tend to be younger to handle the physical demands.
construction jobs are mentally demanding. younger workers have a younger mind and can handle the stress of meeting deadlines and accurately appraising potential jobs.
construction jobs need workers with many years of experience. having more workers with many years of experience will help meet the demands of the job.

Explanation:

Construction jobs are physically demanding. Younger workers are generally more capable of handling physical tasks compared to older workers. This explains why there might be a higher frequency (more workers) in younger age groups as shown in the frequency polygon.

Answer:

Construction jobs are physically demanding. Workers tend to be younger to handle the physical demands.
