3.3, 3.8, 3.10, 3.14, 3.16, 3.28, 3.46, 3.54, 3.56, 3.92

For 3.92, use CALC > RANDOM DATA > BINOMIAL. Remember, p is the probability of success (or proportion of the population possessing the criterion of interest) and n is the number of trials. (You are a simulating taking a simple random sample of size n from a population with proportion p that will answer "yes" to a certain question. The numbers that are generated are the numbers of out n who answer "yes" in each SRS.)

For 3.46a: Table B is just an old-fashioned version of a more modern computer-based pseudorandom number generator. You pick a starting point in the table (for this problem you're asked to start at line 120), and you read the first random number from this starting point. In this case, you're trying to get a random number between 01 and 40, since you want to pick randomly from 40 addresses. You read the first 2 digits off the table (starting at line 120) to pick your first chosen address. (By the way, Table B is on the two pages that are the next-to-last page and next-to-next-to-last page of the book.)
