     A large   real estate company has a department that assesses the market value of homes   that are listed for sale. To become an assessment specialist, a candidate has   the following examination procedure. The candidate and an experienced manager   both look at the same sample of houses and determine the assessed value of   the house on their own. If the assessment of the manager and the trainee are   not significantly different, the trainee passes the course and is certified.   If there is a significant difference, the trainee must take another six weeks   of training. The table below shows the results of the assessments for one   examination (in thousands of $). Test to determine in the trainee has passed   the course or if he requires another six weeks of training. Use alpha = .01   for the test.
