A study was conducted to find out whether 3 specific age groups have different mean body temperatures (oF). The results shown are for 5 randomly selected people from each age group.
| 18-20 year olds | 98.0 | 98.4 | 97.7 | 98.5 | 97.1 |
| 21-29 year olds | 99.6 | 98.2 | 99.0 | 98.2 | 97.9 |
| 30 years and older | 98.6 | 98.6 | 97.0 | 97.5 | 97.3 |
At significance level .05, what is the correct conclusion to the ANOVA F-test?
Group of answer choices
The p-value indicates that each population mean is significantly different from the others.
The p-value indicates that there are no significant differences among the population means.
The p-value equals the significance level, and a determination cannot be made.
The p-value indicates that at least two of the population means differ.
Homework Answers
Answer: The p-value indicates that there are no significant differences among the population means.
Explanation: The p-value of F test is 0.1949. This p-value is greater than 0.05. Hence the p-value indicates that there are no significant differences among the population means.
