A consumer interest group is interested in comparing the speed of four different desktop printers; four different documents are used for the experiment.Each test consists of randomly assigning one printer to one of the documents.The document is printed and the time to print in seconds is recorded.Each printer/document combination is tested.The F-value from an ANOVA is 6.173.What is the P-value?
A) p = 0.0998
B) p = 0.0088
C) p = 0.0901
D) p = 0.9093
E) p = 0.0012
Desktop Printers
Devices designed for printing documents and photos directly from a personal computer, typically fitting on a desk.
Print Speed
The rate at which a printer can produce pages, typically measured in pages per minute (PPM).
P-Value
In statistics, a measure that helps determine the significance of results obtained in hypothesis testing, indicating the probability of observing the given or more extreme results if the null hypothesis is true.
- Identify the correct instances for rejecting or not rejecting null hypotheses by utilizing P-values and α (significance levels).

Final Answer :
B
Explanation :
To find the P-value we need to use statistical software or a table of F-distribution probabilities. However, we can conclude that the P-value is smaller than 0.05 (since the F-value is greater than the critical value of F at alpha=0.05). Therefore, the only possible answer from the choices is B (p = 0.0088).
