A Mechanical Engineer Is Studying Bonding Issues with the Thermal

question 6

Multiple Choice

A mechanical engineer is studying bonding issues with the thermal protection tiles on the Space Shuttle.He wants to see whether there is any difference in the bonding strength between three different compounds.Fifteen tiles are randomly assigned to the three compounds so that each compound is tested on five tiles.Each tile is coated with its assigned compound and bonded to a surface.After a period of time,pull-tests are performed to determine the amount of force needed to break the bond.After collecting the data and analyzing the results,he reports that the F-ratio is 3.097.Assuming that the conditions required for ANOVA are satisfied,what is the P-value? What would you conclude?

• A)p = 0.0827.Reject Using α = 0.05.
• B)p = 0.0827.Do not reject Using α = 0.05.
• C)p = 0.0827.Reject Using α = 0.01.
• D)p = 0.208.Do not reject Using α = 0.05.
• E)p = 0.0827.Do not reject Using α = 0.10.
