The daily low temperature in Ames forecast is in the table below for the next five days. If you pick one of these days at random, what is the expected value of the daily low temperature? Daily low-temperature forecast for Monday-Friday Day M T W R F Temp 28 30 21 22 30 26.8 None of the other answers is correct. 25.5 26.2 24.8 25.0 26.6
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!
