Chapter 4: Q 107. (page 269)

Daytime running lights Canada requires that cars be equipped with 鈥渄aytime running lights,鈥�

headlights that automatically come on at a low level when the car is started. Some manufacturers are now equipping cars sold in the United States with running lights. Will running lights reduce

accidents by making cars more visible? An experiment conducted in a driving simulator suggests that the answer may be 鈥淵es.鈥� What concerns would you have about generalizing the results of such an experiment?

Short Answer

Expert verified

Simulator users are also likely to be in a different mindset than they are when driving in life.

Step by step solution

01

Given information

Daytime running lights can help to decrease accidents by increasing visibility during the day. The usage of daytime running lights also aids drivers in determining the vehicle's size.

02

Concept

Human studies must be approved by an institutional review board in advance. Before taking part, all participants must express their informed consent. Any information regarding the study participants must be kept private.

03

Explanation

It is stated in the question that cars in Canada must have daytime running lights and headlights that automatically turn on at a low level when the car is started. As a result, one of our worries about extrapolating the results of such an experiment is that a driving simulator is unlikely to accurately represent all driving circumstances. Simulator users are also likely to be in a different mindset than they are when driving in real life.

Most popular questions from this chapter

Eat well and exercise Most American adolescents don鈥檛 eat well and don鈥檛 exercise enough. Can middle schools increase physical activity among their students? Can they persuade students to eat

better? Investigators designed a 鈥減hysical activity intervention鈥� to increase activity in physical education classes and during leisure periods throughout the school day. They also designed a 鈥渘utrition intervention鈥� that improved school lunches and offered ideas for healthy home-packed lunches. Each participating school was randomly assigned to one of the interventions, both interventions, or no intervention. The investigators observed physical activity and lunchtime

consumption of fat.

Does eating dinner with their families improve students鈥� academic performance? According to an ABC News article, 鈥淭eenagers who eat with their families at least five times a week are more likely to get better grades in

school.鈥�19 This finding was based on a sample survey conducted by researchers at Columbia University.

Explain clearly why such a study cannot establish a cause-and-effect

relationship. Suggest a lurking variable that may be confounded

with whether families eat dinner together.

Outline a completely randomized design for this experiment. Follow the model of

Figure 4.4.

Getting teachers to come to school Elementary schools in rural India are usually small, with a single teacher. The teachers often fail to show up for work. Here is an idea for improving attendance: give the teacher a digital camera with a tamperproof time and date stamp and ask a student to take a photo of the teacher and class at the beginning and end of the day. Offer the teacher better pay for good attendance, verified by the photos. Will this work? Researchers obtained permission to use 120 rural schools in Rajasthan for an experiment to find out.

(a) Explain why it would not be a good idea to offer better pay for good attendance to the teachers in all120schools and then to compare this year鈥檚 attendance with last year鈥檚.

(b) Write a few sentences describing how you would design this experiment.

Dead trees On the west side of Rocky Mountain National Park, many mature pine trees are dying due to infestation by pine beetles. Scientists would like to

use sampling to estimate the proportion of all pine trees in the area that have been infected.

(a) Explain why it wouldn鈥檛 be practical for scientists to obtain an SRS in this setting.

(b) A possible alternative would be to use every pine tree along the park鈥檚 main road as a sample. Why is this sampling method biased?

(c) Suppose that a more complicated random sampling plan is carried out, and that 35% of the pine trees in the sample are infested by the pine beetle. Can

scientists conclude that 35% of all the pine trees on the west side of the park are infested? Why or why not?
