The time it takes a randomly selected job applicant to perform a certain task has a normal distribution with mean 120 seconds and standard deviation 12 seconds.

1. We are interested in computing the probability that it takes a randomly selected job applicant more than 135 seconds to perform a task. Compute the Z-Score.

2. Find the probability in question #1.

3. The fastest 10% are to be given advanced training. What task time qualifies individuals for advanced training?
