Webthe Normal tables give the corresponding z-score as -1.645. (Negative because it is below the mean.) Hence the raw score is 3 Ie the lowest maximum length is 6.4cm Practice … Web1. Binomial and Poisson distributions can only compute the probability of discrete variables, e.g. number of people, number of tests 2. Normal distributions compute the probability of continuous variables, e.g. time, money, kilometers. This is because the curve of a normal distribution never touches the x-axis. 3.

WebIn probability theory and statistics, the negative binomial distribution is a discrete probability distribution that models the number of failures in a sequence of independent and identically distributed Bernoulli trials before a specified (non-random) number of successes (denoted ) occurs. For example, we can define rolling a 6 on a dice as a … WebThe normal and binomial distribution is important to calculate the mean and also find the possibilities of any given event. Therefore, these distribution systems can act as a tool to find answers to the probability of uncertain events.
