Two chips are being considered for use in a certain system. The lifetime of chip 1 is modeled by a Gaussian random variable with mean 20, 000 hours and standard deviation 4000 hours (The probability of negative lifetime is negligible). The lifetime of chip2 is also a Gaussian random variable but with mean 22,000 hours and standard deviation 1000 hours. Which chip is preferred if the target lifetime of the system is 20.000 hours?

Can any one me with the answers to these questions asap?
