What is the distribution of X? X~ N, What is the distribution of hypen over the x ~N. For a single randomly selected steel rod, find the probability that the length is between 198.5-cm and 198.6-cm. For the bundled of 44 rods, find the probability that the average length is between 198.5-cm and 198.6-cm. A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 198.4-cm and a standard deviation of 7.0 -cm. For shipment, 44 steel rods are bundled togher.
Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
