Researchers sent out a survey to U.S. war veterans that asked a series of questions, including whether individuals surveyed were smokers or nonsmokers (Seltzer et al. 1974). They found that nonsmokers were 27% more likely than smokers to respond to the survey within 30 days (based on the much larger number of smokers and nonsmokers who eventually responded). Hypothetically, if the study had ended after 30 days, what effect would this have on the estimate of the proportion of veterans who smoke? Select the correct description of the effect. The estimate would be biased because of the underestimation of the true proportion of smokers. The estimate would be biased because of the overestimation of the true proportion of smokers. The estimate would not be biased because capping at 30 days would not change the estimated proportion of smokers. The estimate would not be biased because the sample of veterans is a volunteer sample.

Urban Travel Times Population of cities and driving times are related, as shown in the accompanying table, which shows the 1960 population N, in thousands, for several cities, together with the average time T, in minutes, sent by residents driving to work. City Population N Driving time T Los Angeles 6489 16.8 Pittsburgh 1804 12.6 Washington 1808 14.3 Hutchinson 38 6.1 Nashville 347 10.8 Tallahassee 48 7.3 An analysis of these data, along with data from 17 other cities in the United States and Canada, led to a power model of average driving time as a function of population. a Construct a power model of driving time in minutes as a function of population measured in thousands b Is average driving time in Pittsburgh more or less than would be expected from its population? c If you wish to move to a smaller city to reduce your average driving time to work by 25, how much smaller should the city be?
What determines how much money a family spends on holiday? In a survey, a sample of 30 families were asked to keep a record of their spending during a one-week holiday and report their total spending at the end of the week. The researchers hypothesised that wealthier families tend to spend more, and that families who tend to spend most of the time in one town tend to spend less than those who travel around to see sight at several different places. Therefore, the respondents were asked to report the net monthly income of the family as well as the number of different settlements (villages, towns, and cities) that they visited during the week. A multiple linear regression model revealed that both income and the amount of travelling are significantly related to total spending. The researchers, however, also hypothesised that the two independent variables may interact. The printout below shows the SPSS output for fitting an interaction model to the data. < Model 1 Model 1 R .866ª Model 1…
Recent research indicates that the effectiveness of antidepressant medication is directly related to the severity of the depression (Khan, Brodhead, Kolts & Brown, 2005). Based on pretreatment depression scores, patients were divided into four groups based on their level of depression. After receiving the antidepressant medication, depression scores were measured again and the amount of improvement was recorded for each patient. The following data are similar to the results of the study.

Researchers investigated factors that influenced how much people like each other based on first meeting. They were particularly interested in the effects of eye-to-eye contact and smiling. They collected data from 20 participants. Each participant was asked to wait in a small room while the experimenter went next door, ostensibly to gather the materials needed for the study. While the participant was waiting, a confederate of the experimenter entered the room and sat in a chair facing the participant, and asked "Are you waiting for the experiment?". Immediately after asking the question, the confederate smiled at, and/or looked directly into the eyes of, the participant. This was done in four conditions: for five participants the confederate smiled and looked into the participant's eye, for five participants the confederate smiled but did not look into the participant's eye, for five participants the confederate did not smile but did look into the participant's eyes, and for five…
