7)- Utilizing what you know for standard normal distributions, solve this problem. In the Journal of Engineering for Industry, May 1993, a study was documented on feed paper separation. Assume the friction coefficient for a certain copier system is normally distributed, with u = 0.55 and o = 0.13. While the system is operating, the friction coefficient is measured at a randomly selected time. 1. Find the probability that the friction coefficient falls between 0.53 and 0.56. 2. How likely is it to observe a friction coefficient below 0.5?
