FINISH Section 4.3 Example: A process manufactures bolts whose diameters are normally distributed with mean 1.5 cm and standard deviation 0.1 cm. What percentage of bolts manufactured fall between 1.25 and 1.65 cm? A bolt is selected at random. What is the probability it has a diameter greater than 1.6 cm? Five bolts are selected at random. What is the probability three of them have a diameter greater than 1.6 cm? What is the 25th percentile of the standard normal distribution? What diameter corresponds to the 75th percentile of a N(10, 2)?
