Use the Normal Probability Distribution table or the built-in functions of your calculator to find: a. What percent of male adults are taller than 6 feet (72 inches)? B.Because of the high cost of leather, the company has decided they cannot profitably make leather pants in all sizes. Use the Normal Probability Distribution table or the built-in functions of your calculator to find the heights corresponding to the following percentages. These are the heights of the shortest and tallest males who can purchase leather pants from this company. The bottom 9% The upper 7%
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!
