What key feature distinguishes nonparametric from parametric tests?

Question 2

A manufacturer of printers claims that their color cartridge will print an average of 200 4-by-6 photos with a standard deviation of 60 photos. A random sample of 40 customers counted the number of photos printed with one cartridge. If the manufacturer's claim is correct, what is the probability that the average customer printed at least 210 pages with one cartridge?
