T3-M4, a legendary astromech droid from the Old Republic, wants to examine the effectiveness of his generated computer spikes. Computer spikes can allow a user to hack into a computer. As it so happens, the time-to-hack of his spikes can be modeled by a Normal distribution with a mean of 20 microseconds and a standard deviation of 3 microseconds. Answer the following questions. Do not include units.
