Textbook Question
Chapter 11, Problem 90CR
Dentists make many people nervous. To see whether such nervousness elevates blood pressure, the blood pressure and pulse rates of 60 subjects were measured in a dental setting and in a medical setting (“The Effect of the Dental Setting on Blood Pressure Measurement,” American Journal of Public Health [1983]: 1210–1214). For each subject, the difference (dental-setting blood pressure minus medical-setting blood pressure) was calculated. The analogous differences were also calculated for pulse rates. Summary data follow.
- a. Do the data strongly suggest that true mean blood pressure is greater in a dental setting than in a medical setting? Use a level 0.01 test.
- b. Is there sufficient evidence to indicate that true mean pulse rate in a dental setting differs from the true mean pulse rate in a medical setting? Use a significance level of 0.05.

If a newborn lab rat receives a hormone and its weight (in ounces) is converted into a z score that is greater than +2.00, what would the researcher most likely conclude about whether or not the hormone had an effect on the rat's weight?
To determine the effectiveness of an oil additive, a testing firm purchased two cars of the same make, year, and model, and drove each a distance of 30,000 miles using the same kind of gasoline, the same kind of oil, the same driver, under the same road conditions. The oil in one engine included the additive, whereas the oil in the other engine did not. At the end of the test, the engines of both cars were dismantled, and it was found that the engine that contained the additive had less wear. The testing firm concluded that the oil additive caused the reduced wear.
In a classic study, Shrauger (1972) examined the effect of an audience on performance for two groups of participants: high self-esteem and low self-esteem individuals. The participants in the study were given a problem-solving task with half of the individuals in each group working alone and a half working with an audience. Performance on the problem-solving task was measured for each individual. The results showed that the presence of an audience had little effect on high self-esteem participants but significantly lowered the performance for the low self-esteem participants.
a. How many factors does this study have? What are they? b. Describe this study using the notation system that indicates factors and numbers of levels of each factor.
