Final answer:
Sally is out of the labor force as she is not able to look for jobs due to illness.
Step-by-step explanation:
To determine whether Sally is in the labor force or not, we need to consider the conditions for being classified as unemployed or out of the labor force. According to the U.S. Bureau of the Census, to be classified as unemployed, a person must be without a job, currently available to work, and actively looking for work in the previous four weeks. However, if a person does not have a job and is not currently available to work or has not actively looked for work in the last four weeks, they are counted as out of the labor force.
In Sally's case, it is mentioned that she is not able to look for jobs due to illness. Therefore, Sally is out of the labor force, as she does not meet the criteria for being classified as unemployed.
