A company developing scanners to search for hidden weapons at airports has concluded that a new device is significantly better than the current scanner. The company made this decision based on a P-value of 0.018. Explain the meaning of the P-value in this context.

A If the new scanner has the same effectiveness as the current scanner, there is a 1.8% chance of observing a rate of success this large or larger in finding hidden weapons using the new scanner in a sample of the same size by natural sampling variation alone.

B. If the new scanner is more effective than the current scanner, there is a 1.8% chance of observing a rate of success this large or larger in finding hidden weapons using the new scanner in a sample of the same size by natural sampling variation alone.

C. The P-value0.018 is the probability that the new scanner is no more effective than the current scanner.

D. The P-value 0.018 is the probability that the new scanner is more effective than the current scanner. E. If the new scanner has the same effectiveness as the current scanner, there is a98.2% chance of observing a rate of success this large or larger in finding hidden weapons using the new scanner in a sample of the same size by natural sampling variation alone.
