Final answer:
With a p-value of 0.912, you fail to reject the null hypothesis, concluding there is no significant difference in the mean building heights among Nashville, Memphis, and Chattanooga.
Step-by-step explanation:
When you run a one-way ANOVA and find an omnibus p-value of p=0.912, your decision about the null hypothesis depends on its comparison with your chosen significance level, often alpha = 0.05. Because the p-value is greater than the alpha level, you do not have enough evidence to reject the null hypothesis. Therefore, the correct answer is:
- Fail to reject; the mean height of buildings in all cities are the same.
The one-way ANOVA was conducted to determine if there was a difference in the mean heights of buildings between Nashville, Memphis, and Chattanooga. Given the high p-value, it indicates that there is no significant difference in the mean heights between the cities, suggesting that any observed differences are likely due to random variation rather than a true difference in populations.
