Question 2 of 15 • Probability and Statistics with Applications Honors Sem-1-FL-1210300 (2024-2025)
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 salary, 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?
Answer
A
The survey will provide a reasonable estimate of mean annual salary because all graduates were sent the email survey.
B
The survey will likely overestimate mean annual salary because those with higher salaries may be more likely to respond to the survey.
C
The survey will likely underestimate mean annual salary because there may be more graduates with lower salaries than higher salaries.
D
The survey will likely overestimate the mean annual salary because the email was only sent to graduates with jobs in their chosen field.
