Suppose The total daily carbohydrate intake and for all boys age 13 and 15 years old in the US is normally distributed with a mean of 125 grams Per thousand calories with a standard deviation of 25 grams per thousand calories. approximately what percent boys boys in the age range have daily carbohydrate intake below 75 grams per thousand calories? 50% 18.65% 2.5%
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!
