An employer offers its employees a program that will provide up to four free psychological counseling sessions per calendar year. To evaluate satisfaction with this service, the counseling office mails questionnaires to every 10th employee who used the benefit in the prior year. There were 1000 employees who used the benefit. Therefore, 100 surveys were sent out. However, only 25 of the potential respondents completed and returned their questionnaire.

a) The population for the study is the 1000 employees who used the psychological counseling benefit in the prior year.
b) The sample is the 100 employees who were selected to receive the questionnaire, specifically the 25 who completed and returned it.
c) The concern raised by the fact that only 25 of the 100 questionnaires were completed and returned is that the sample may not be representative of the entire population. This low response rate could introduce bias into the results, as the views of the 25 respondents may not accurately reflect the views of all 1000 employees who used the service. This could limit the validity and generalizability of the study's findings.
