There will be three assignments (worth a total of 10%). The tentative due dates are October 6th, November 3rd and December 1st. All assignments are due at the beginning of lecture. No late assignments will be accepted.

### Assignment 1

Due Tuesday, October 6th at 7pm. No late assignments will be accepted.- From the textbook do the following questions: 1.19, 1.32, 1.38, 1.66,
1.68, 1.114, 1.116, 1.154, 1.166.
- Note that we have not yet covered the material for 1.116, but we will do so in the next lecture.
- In question 1.166, find the mean and median by hand (or using a calculator), and show the steps used.
- Question 1.19 asks you to create some bar graphs. You may do this by hand, but you may also use Excel. Here is a file that explains how to do bar graphs in Excel.

- Here (or here, in slightly different format) is some data
on survival times for men and women
drawn from the life tables available from the Statistics Canada website
for the year 2002. In the data files, the first column indicates the
gender of each individual, with 1 for men, and 0 for women; the second
column gives the number of years each individual lived.
- Using the tools learned in class, either support or argue against the claim "women live longer than men". Be succinct in what you choose to report.
- Name fields/agencies/places that would be interested in this type of information.
- Do you notice anything unusual about the dataset?

### Assignment 2

### Assignment 3

Due Tuesday, December 8th at 7pm. No late assignments will be accepted.- Here is a list of student numbers for our class. Use Excel to randomly select 20 students from this list (recall, the handout on how to do this is still posted in the computing section). Hand in a print out of the Excel sheet, and clearly indicate which students were selected. Remember - everyone should have a different answer here!
- Does 99 cent pricing really work? Stores always price things as 399$ and not 400$, or 9.99$ instead of 10$. Outline a simple statistical experiment/study to determine if this pricing works. Point out the statistical tools you used in your design, and note their importance in the experiment/study.
- From the textbook, do the following questions: 3.128, 4.30, 4.38, 4.44.
- From the textbook, also do the following questions: 4.47 (on page 262), 4.64, 4.74 (do the standard deviations here as well), 4.80.
