A study found that the average stopping distance of a school bus traveling 50 miles per hour was 264 feet. A group of automotive engineers decided to conduct a study of its school buses and found that, for 20 buses, the average stopping distance of buses traveling 50 miles per hour was 262.3 feet. The standard deviation was 3 feet. To test the claim that the average stopping distance of the company’s buses is actually less than 264 feet, State...

To investigate the fluid mechanics of swimming, twenty swimmers each swam a specified distance in a water-filled pool and in a pool where the water was thickened with food grade guar gum to create a syrup-like consistency. Velocity, in meters per second, was recorded and the results are given in the table below.

In The New York Times, there is a column called “The Ethicist,” where some writer for the newspaper gives arguments in response to questions that are posed by readers. In the question below titled “Test Prep or Perp?,” Randy Cohen is the writer who gives an argument in reply to someone’s question about whether it’s ethical to use Adderall (the person’s name is withheld) to help take the L.S.A.T. (Law School Admission Test). I think that there is at least...

Suppose Diana, an educational researcher at a local university, wants to test the impact of a new Spanish course that integrates cultural-immersion teaching techniques with standard teaching practices. She selects a simple random sample of 62 freshmen and divides them into 31 pairs, matched on IQ and high school GPA. She randomly selects one member of each pair to take the new course, while the other member in the pair takes the traditional course. Next, Diana records the course grade,...

A recent article (Hauser, Glynn, and Wood, 2007) described a study that investigated whether rhesus monkeys have some ability to understand gestures made by humans. In one part of the study, the experimenter approached individual rhesus monkeys and placed two boxes an equal distance from the monkey. The experimenter then placed food in one of the boxes, making sure that the monkey could tell that one of the boxes received food without revealing which one. Finally, the researcher made eye...
