Question

A trade school would like to measure the long-term success of their graduates after they leave the school. The school

emails a survey requesting information from graduates about their work experience. One question asks graduates to

share their annual salar), and the results of the question will be shared in a brochure for incoming students. Is it likely

that the survey results will provide an accurate estimate of mean annual salary for all of the school's graduates?
