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

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).
