Practice: You always feel like you?re getting underpaid compared to everyone else in your same position. Assume that the pay of the employees at your level is normally distributed with a mean of $40,000 and a standard deviation of$5,000. What pay separates the top 22% from the other 78%?

Practice: It?s always hard to tell if sour cream has gone bad. Assume the average sour cream can last seven weeks with a standard deviation of 10 days, and that this distribution is normal. How many days does it take for the fastest rotting 14% of sour cream to go bad?
