In an automotive body-welding line, delays encountered during the process can be modeled by various probability distributions. (Source: R.R. Inman, “Empirical Evaluation of Exponential and Independence Assumptions in Queueing Models of Manufacturing Systems, “Production and Operations Management, Vol. 8, 409-432 (1999). The processing time for the automatic piercing station has a normal distribution with mean 36.2 sec and standard deviation 2.108 sec. Find the probability that the next operation of the piercing station will take between 35 and 40 sec.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
