2. The student council wants to know what activities would be supported by the student body. Decisions about activities are often made on the basis of survey information. Let's say that a survey was sent out to the student body via emails listed in the school's data base. The survey asked three questions: • Do you support the student council's decision to hold a fund raiser for the food bank? • Do you support the student council's decision to have a school social? • Do you support the student council's decision to offer peer mentoring? Below is a Venn diagram showing the results of the students who responded to the survey. Each circle represents the students who supported that decision. Use the diagram to answer the following questions. For each question show all calculations required and state your conclusion in a complete sentence or short paragraph.

The business provides breakfast and brunch food, via carts parked along sidewalks, to people in the business district of the city. Being an experienced businessperson, Maria provides incentives for the four salespeople operating the food carts. This year, she plans to offer monetary bonuses to her salespeople based on their individual mean daily sales. Below is a chart giving a summary of the information that Maria has to work with.

Suppose you just graduated with an accounting degree and are trying to choose an accounting firm to begin your career. You spent hours researching many firms and have narrowed your search down to three (i.e. Aguilar, Brown and Cheng). You have surveyed accountants to determine if the average incomes at each firm are equal between each of your top three choices. Obviously you want to join the firm with the highest average pay. Below are a sample of salaries (i.e. eight individuals from each firm) enabling you to test the hypothesis that the average pay (in thousands of $) is equal between employers. Use Fisher's LSD procedure (if necessary) to test whether there is a significant difference between any of the firms.
