WebBinomial probability distribution A disease is transmitted with a probability of 0.4, each time two indivuals meet. If a sick individual meets 10 healthy individuals, what is the probability that (a) exactly 2 of these individuals become ill. (b) less than 2 of these individuals become ill. (c) more than 3 of these individuals become ill.

WebA z-test is used only if your data follows a standard normal distribution. In this case, your data follows a binomial distribution, therefore a use a chi-squared test if your sample is large or fisher's test if your sample is small. Edit: My mistake, apologies to @Dan. A z-test is valid here if your variables are independent. WebIn the first case. p ( z) = ∑ i = 0 n 1 m ( i + z, n 1, p 1) m ( i, n 2, p 2) since this covers all the ways in which X-Y could equal z. For example when z=1 this is reached when X=1 and Y=0 and X=2 and Y=1 and X=4 and Y=3 …

WebJan 18, 2024 · Ratio distribution is a probability distribution representing the ratio of two random variables, each usually having a known distribution. Currently, there are results when the random variables in the ratio follow (not necessarily the same) Gaussian, Cauchy, binomial or uniform distributions.
