Chapter 1: Q17 (page 11)

In Exercises 17鈥�20, refer to the sample of body temperatures (degrees Fahrenheit) in the table below. (The body temperatures are from a data set in Appendix B.)

Subject


12345
8 AM9798.597.697.798.7
12 AM97.697.89898.498.4

Context of the Data: Refer to the table of body temperatures. Is there some meaningful way in which each body temperature recorded at 8 AM is matched with the 12 AM temperature?

Short Answer

Expert verified

Yes, each body temperature recorded at 8 AM and 12 AM belongs to a common experimental unit.

Step by step solution

01

Given information

The table shows body temperatures recorded twice a day for five subjects.

02

The interpretation of the table

The rows show the values recorded at 8 AM and 12 AM.

Any pair of values taken at 8 AM and 12 AM is recorded against a subject of the study. The columns in the table represent the subjects proposed to be recorded for the study.

03

Meaning of matched observations

A matched set of observations is recorded in a way that each observation is related to a common unit of the experiment (or subject).If only two sets of variables are recorded from each experimental unit, they are referred to as paired or matched paired values.

04

Step 4:The relationship between the body temperatures

As per the interpretation of the table, the body temperatures are matched with one of the subjects.

Thus, the body temperatures are paired values.

Percentages in Negotiations When the author was negotiating a contract for the faculty and administration at a college, a dean presented the argument that if faculty receive a 4% raise and administrators receive a 4% raise, that鈥檚 an 8% raise and it would never be approved. What鈥檚 wrong with that argument?

Statistical Significance and Practical Significance. In Exercises 13鈥�16, determine whether the results appear to have statistical significance, and also determine whether the results appear to have practical significance.

MCAT The Medical College Admissions Test (MCAT) is commonly used as part of the decision-making process for determining which students to accept into medical schools. To test the effectiveness of the Siena MCAT preparation course, 16 students take the MCAT test, then they complete the preparatory course, and then they retake the MCAT test, with the result that the average (mean) score for this group rises from 25 to 30. There is a 0.3% chance of getting those results by chance. Does the course appear to be effective?

Question: Reported versus Measured. In a survey of 1046 adults conducted by Bradley Corporation, subjects were asked how often they wash their hands when using a public restroom, and 70% of the respondents said 鈥渁lways.鈥�

a. Identify the sample and the population.

b. Why would better results be obtained by observing hand washing instead of asking about it?

Correlation. One study showed that for a recent period of 11 years, there was a strong correlation (or association) between the numbers of people who drowned in swimming pools and the amounts of power generated by nuclear power plants (based on data from the Centers for Disease Control and Prevention and the Department of Energy). Does this imply that increasing power from nuclear power plants is the cause of more deaths in swimming pools? Why or why not?
