A researcher at a Premier University is trying to decide whether to enter a one-year teacher'scollege and become a high school teacher or go to graduate school, obtain an MS and Ph.D., andbecome a university professor. After careful consideration, he concludes that the decision shouldbe made on the basis of the average annual income of two groups ten years after getting thebachelor's degree. In particular, he will become a university professor unless there is enoughevidence to allow him to conclude that high school teacher earn more money. The researchertakes a sample of 50 university professors and 50 high school teachers, all of whom graduatedwith their bachelor's degrees ten years ago and determines their annual income. The results aresummarized in the accompanying table:Mean and variance of annual incomeHigh school teacherX = 43.7si= 11.8University Professorx = 41.5si= 46.3At the 5 % significance level, should he become a University Professor or a High School Teacher?

Consider the following bargaining problem: Two siblings Naa and Nii have to have Gh20 million they inherited from their parents between them. Naa gets to make an initial offer. Nii then gets to respond by either accepting Naa's initial offer or offering a counter offer. Finally, Naa can respond by either accepting Nii's offer or making a final offer. If Nii does not accept Naa's final offer both Nii and Naa get nothing. Nii discounts the future at 10% (i.e., future earnings are with 10% less than current earnings) while Naa discounts the future at 20%. Calculate the Nash equilibrium of this bargaining problem.
