the ability to determine the age of some individuals can be difficult if there are not quality government records of birth bone growth takes place at the growth plates at the end of long bones once all growth plates fuse growth stops and an individual is considered a biological adult the age at which growth plates fuse for males is approximately normally distributed with a mean of 19.2 years and a standard deviation of 15.3 months what is the probability of a males growth plates fuse after age 21
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!
