To collect data in an introductory statistics course, recently i gave the studentsa questionnaire. one question asked whether the student was a vegetarian. of25 students, 0 answered "yes." they were not a random sample, but let us usethese data to illustrate inference for a proportion. (you may wish to refer tosection 1.4.1 on methods of inference.)

After graduation, you plan to work for dynamo corporation for 12 years and then start your own business. you expect to save and deposit $7,500 a year for the first 6 years (t = 1 through t = 6) and $15,000 annually for the following 6 years (t = 7 through t = 12). the first deposit will be made a year from today. in addition, your grandfather just gave you a $32,500 graduation gift which you will deposit immediately (t = 0). if the account earns 9% compounded annually, how much will you have when you start your business 12 years from now?
