A study of Brown Bag Company's payment practices showed that the company pays its vendors 20 days after the accounting department receives the invoice. The standard deviation is 5 days. Assuming that there is a normal distribution across the company's payments, what percent of the invoices are paid within 15 days of receiving them? Based on your answer, recommend an effective payment strategy for the company.
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!
