STUDY GUIDE 4. An engineering student measures the corrosion of steel in an acidic solution. An average of 0.06 g of steel is lost during the corrosion process. The standard deviation is 0.015 g. What is the probability that more than 0.03 g of a particular steel is lost during the corrosion process? 5. The typing speed of employees in a certain office is 42.75 wpm with standard deviation of 12.5 wpm. If there are 300 employees in the office, how many people can type more than 67.75 wpm?
