I ./| Just Checking As we noted a few chapters ago, the Pew Research Center (www.pewresearch.org) reports that they are actually able to contact only 76% of the randomly selected households drawn for a telephone survey. 1. Explain why these phone calls can be considered Bernoulli trials. 2. Which of the models of this chapter (Geometric, Binomial, Normal) would you use to model the number of successful contacts from a list of 1000 sampled households? Explain. 3. Pew further reports that even after they contacted a household, only 38% agree to be interviewed, so the probability of getting a completed interview for a randomly selected household is only 0.29. Which of the models of this chapter would you use to model the number of households Pew has to call before they get the rst completed interview? 4. Suppose that in the course of a year, legitimate survey organizations (not folks pretending to take a survey but actually trying to sell you something or change your vote) sample 70,000 of the approximately 107,000,000 households in the United States. You wonder if people from your school are represented in these polls. Counting all the living alumni from your school, there are 10,000 house- holds. How would you model the number of these alumni households you'd expect will be contacted next year by a legitimate poll
