1 Webex

I'll have 2 laptops and an ipad for today's class. We'll see what works.

2 Worked out examples and problems

perhaps some of these.

1. 5.33, p 267

2. ex 7.1 p360

3. Section 7.2, p365.

   Note: Chebyshev inequality, Eqn 4.76, p 182. says

   \(P[ | X-m | \ge a ] \le \sigma^2/ a^2\)

   Eqn 7.20, p 366 is useful:

   \(P[ | M_n-\mu | < \epsilon ] \ge 1 - \sigma^2 / (n \epsilon^2)\)

4. Example 7.10, 7.11, 7.12.

5. 7.14a, p 403.

6. 8.3 p 471.

7. 8.4 p 471.

   Normal probability tables were given in class 20.

8. 8.10, p 472.

:: #. 8.24, p 474.

3 Useful tables

TABLE 3.1 Discrete random variables is page 115.

TABLE 4.1 Continuous random variables is page 164.

4 Normal distribution table

For your convenience. I computed it with Matlab.:
