Question
![A company claims to have invented a hand-held sensor that can detect the presence of explosives
inside a closed container. Law enforcement and security agencies are very interested in
purchasing several of the devices if they are shown to perform effectively. An independent
laboratory arranged a preliminary test. If the device can detect explosives at a rate greater than
chance would predict, a more rigorous test will be performed. They placed four empty boxes in
the corners of an otherwise empty room. For each trial they put a small quantity of an explosive
in one of the boxes selected at random. The company's technician then entered the room and
used the sensor to try to determine which of the four boxes contained the explosive. The
experiment consisted of 50 trials, and the technician was successful in finding the explosive 16
times. Does this indicate that the device is effective in sensing the presence of explosives, and
should undergo more rigorous testing?
a) Test an appropriate hypothesis and state your conclusion.
b) Was your test one-tail upper tail, lower tail, or two-tail? Explain why you chose that kind
of test in this situation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff6782647-6bf4-4f12-8cfa-ee9891665231%2Fbd042fb5-7130-4116-ac2e-0e999958d0c6%2Fujlf1p_processed.png&w=3840&q=75)
