1) Find the area under the standard normal curve to the left of z = 1.9. 2) Find the probability P(z > -0.59) using the standard normal distribution. 3) Find the z value to the right of the mean so that 62.93% of the area under the distribution curve lies to the left of it. 4) A normal population has a mean = 33 and standard deviation What is the probability that a randomly chosen value will be greater than 30? 5) At a large department store, the average number of years of employment for a cashier is 5.7 with a standard deviation of 1.8 years, and the distribution is approximately normal. If an employee is picked at random, what is the probability that the employee has worked at the store for over 10 years
