ces are labeled containing 300 g of cereal. The machine filling the boxes produces weights that are normally distributed with standard deviation 10 g. OIf the target weight is 300 g, what is the probability that the machine produces a box with less than 275 g of cereal? (Round your answer to three decimal places.) OSuppose a law states that no more than 4% of a manufacturer's cereal boxes can contain less than the stated weight of 300 g. At what target weight should the manufacturer set its filling machine? (Round your answer to
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!
