Complete the following questions before our next class.

(red textbook)
Exercise 12J questions 1, 3, 6, 13, 17 (13 and 17 are challenge questions)

Also (while we almost got to this yesterday), we can also calculate the variance and standard deviation (and the mean value) for a binomial distribution (which then answers the question: if we were to repeat this experiment several times, how “spread out” would our results be?). The formulas for these are given in the textbook (and the formula booklet). All you need to know is when (and how) to use them. See the questions below.

(black textbook)
20F questions 2, 4, 5

Complete the following questions before our next class.

(red textbook)
Exercise 12E question 4
Exercise 12F questions 2 and 4
Exercise 12G question 1
Exercise 12H question 3

Read Chapter 11 of the red textbook and come prepared after the break with any questions you have about that material. Pay particular attention to 11B (the definitions in 11A for types of sampling error are less critical, but you should be able to recognize when a sample is likely to be biased).

Then, complete the following questions.

Exercise 11D questions 2 and 4
Exercise 11F question 1

Exercise 12A questions 2b and 13
Read section 12B.
Exercise 12C questions 2 and 5
Exercise 12D questions 6 and 7
