Alio immigrated to the United States 4 years ago with her family. She is a first-year graduate student studying individual opinions of governance. Unfortunately, Alio put off her research until she went home to visit her family over Thanksgiving break. Knowing most people in the neighborhood, the town, her church, etc., Alio thought she could quickly come up with at least 100 survey participants if she went from door-to-door and approached people during her weekly activities. Upon reading Alio’s research paper, the professor immediately recognized a problem with the data. Alio was marked down for failing to account for _____________________.

A school district in Sarnia is considering where to locate its central office.  Note: the office must be located at an existing school for cost reasons. There are five schools in the district, with locations and size given in the following table. Location Size (Enrollment) (x,y) Coordinates x-calcs y-calcs A 2,500 (5,5)     B 1,000 (0,5)     C 10,000 (0,0)     D 4,500 (5,0)     E 7,500 (2,1)               Required:   1. Use the Centre-of-Gravity method to determine at which school the central office should be located to minimize the average distance between the office and students. [5 marks]   2. Consider one intangible (non-financial) cost that should be considered when making this location decision. [1 mark] NOTE: X-calc and y-calc values must be shown to receive marks.
