Find the null and alternative hypotheses for this situation: XYZ Corporation has taken a sample of 25 former employees and found that the mean length of employment at the corporation before retirement was 21.5 years with a standard deviation of 2.5 years. Management wants to determine whether the mean employment length for all XYZ employees is more than 20 years.
Homework Answers
