Chapter 1 Solutions Develop Your Skills 1.1 1. You would have to collect these data directly from the students, by asking them. This would be difficult and time-consuming, unless you are attending a very small school. You might be able to get a list of all the students attending the school, but privacy protection laws would make this difficult. No matter how much you tried, you would probably find it impossible to locate and interview every single student (some would be absent because of illness or work commitments or because they do not attend class regularly). Some people may refuse to answer your questions. Some people may lie about their music preferences. It would be difficult to solve some of these problems. You might ask for the school's cooperation in contacting students, but it is unlikely they would comply. You could offer some kind of reward for students who participate, but this could be expensive. You could enter participants' names in a contest, with a music-related reward available. None of these approaches could guarantee that you could collect all the data, or that students would accurately report their preferences. One partial solution would be to collect data from a random sample of students, as you will see in the discussion in Section 1.2 of the text. Without a list of all students, it would be difficult to ensure that you had a truly random sample, but this approach is probably more workable than a census (that is, interviewing every student). 2. Because you need specific data on quality of bicycle components, you would need to collect primary data. Customer complaints about quality are probably the only source of secondary data that you would have. 3. Statistics Canada has a CANSIM Table 203-0010, Survey of household spending (SHS), household spending on recreation, by province and territory, annual, which contains information on purchases of bicycles, parts and accessories. There is a U.S. trade publication called "Bicycle Retailer & Industry News", which provides information about the industry. See http://www.bicycleretailer.com/. Access is provided through the Business Source Complete database. Industry Canada provides a STAT-USA report on the bicycle industry in Canada, at
