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!

Interpret the mean, median, and mode results using this table. Descriptions: Landfill is the number of disposal sites for solid wastes to be recycled. In the process, it entails soil destruction, thus, emitting greenhouse gases. Acid pertains to the emission of sulfur dioxide and nitrogen oxide measured in thousand tons. This results from the burning of fuels by electric utilities or utility coal consumption which is considered as a contributor to the greenhouse emission. Greenhouse is the amount of greenhouse gases in their carbon monoxide equivalent in terms of heating value, wherein heating value is the amount of heat trapped by CO2, measured in million tons.
