A battery has a lifetime that is approximately normally distributed with a mean of 600 hours and a standard deviation of 50 hours. Suppose you purchased one of these batteries and it only lasted for 400 hours. Which of the following conclusions is the most appropriate given this information?
A. Your battery is likely defective since such poor performance is extremely unlikely.
B. Your battery is definitely below average since it is below the mean.
C. There is a 50-50 chance of a battery having a worse than average performance, so the performance of your battery is not surprising.
