### Computing Normal Probabilities with a Given Z Score

1. Given that z is a standard normal random variable, compute the following probabilities. a. p (z = 2.0) b. p (z ≥ 1.4) c. p (-1.0 < z < 0.5) d. p (1.0 < z < 1.2) 2. The time needed to drive from city A to city B is normally distributed with a mean of 180 minutes and standard deviation of 20 minutes. a. Wha
