An Electrical Engineer Wants to Compare the Resistance of Four

question 13

Multiple Choice

An electrical engineer wants to compare the resistance of four types of wire made from different materials.Five wires of equal lengths and cross sectional areas are prepared for each of the four wire types.Each section of wire is randomly tested by sending a current through the wire and measuring the resistance.After collecting the data and analyzing the results,she reports that the F-ratio is 1.076.Assuming that the conditions required for ANOVA are satisfied,what is the P-value? What would you conclude?

• A)p = 0.0871.Do not reject Using α = 0.05.
• B)p = 0.3872.Do not reject Using α = 0.05.
• C)p = 0.0871.Reject Using α = 0.10.
• D)p = 0.3872.Reject Using α = 0.05.
• E)p = 0.3872.Reject Using α = 0.25.
