Running red lights The sample described in Exercise 31 produced a list of 5024 licensed drivers.

The investigators then chose an SRS of 880 of these drivers to answer questions about their driving habits.

One question asked was: “Recalling the last ten traffic lights you drove through, how many of them were red when you entered the intersections?” Of the 880 respondents, 171 admitted that at least one light had been red. A practical problem with this survey is that people may not give truthful answers. What is the likely direction of the bias? Explain.
