Chapter 1: Q17BSC (page 1)

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.)

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.

IQ Scores Most people have IQ scores between 70 and 130. For $39.99, you can purchase a PC or Mac program from HighIQPro that is claimed to increase your IQ score by 10 to 20 points. The program claims to be 鈥渢he only proven IQ increasing software in the brain training market,鈥� but the author of your text could find no data supporting that claim, so let鈥檚 suppose that these results were obtained: In a study of 12 subjects using the program, the average increase in IQ score is 3 IQ points. There is a 25% chance of getting such results if the program has no effect.
