Chapter 1: Q20BSC (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.).

Conclusion If we analyze the listed body temperatures with suitable methods of statistics, we conclude that when the differences are found between the 8 AM body temperatures and the 12 AM body temperatures, there is a 64% chance that the differences can be explained by random results obtained from populations that have the same 8 AM and 12 AM body temperatures. What should we conclude about the statistical significance of those differences?

Short Answer

Expert verified

The results seem to be insignificant statistically.

Step by step solution

01

Given information

For the paired set of temperatures recorded at 8 AM and 12 AM, it is concluded that there are 64% chances that the samples from the population can explain the differences between the temperatures.

02

Meaning of statistical significance

The results from a study are concluded to be statistically significant if they have rare chances to appear in the study. The probability of obtaining the results under the assumption of no effect is lesser than 5%.

03

Explanation of statistical significance

In this situation, the chances of obtaining differences between body temperatures through a certain statistical method are 64%.

The value is larger than 5% and signifies that the result is not unusual.

Thus, it can be concluded that the result for differences between the body temperatures is not statistically significant.
