Apparently people are emailing lots of different document formats to Becky, making grading cumbersome. So, instead of emailing, **please print your Excercise and turn it in at the beginning of class on Thursday** (9/5). Sorry for any confusion.

- Complete Problem 2.1 on p. 22
- Complete Problems 2.7 and 2.9 on p. 28-29
- Install the “Analysis TookPak” – see p 49 for instructions
- Use the Excel database (downloaded last week: black_7e_excel_database) to complete Analyzing the Database problems 1, 2 and 3 on p. 47-48.

**Help for problem 2.1.** I entered the data in Excel, created bins and made histograms. Hopefully this will help you understand the problem. You can use this data and the histograms for parts a and b. But, part c is up to you. Which is more useful – 5 or 10 bins? Why? Link to Excel file: Ex2_2-1
