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.

Question

a) If 30 % of the hack times are greater than A microseconds, what is A to one decimal place?

b) What percent of the times are predicted to be between 18 and 20 microseconds? 

Report the percentage to two decimal places.

c) What percent of the times are predicted to be between 18 and 20 microseconds? 

Report the percentage to two decimal places.

d) If 60 % of the hack times are predicted to be between 17 and B microseconds, what is B to one decimal place?

Note: Avoid rounding until the very end. Store intermediary numbers as a variable to use in your calculator. 

e) What is the probability that the hack times are typical?

Round your answer to two decimal places.
