WebThe time is known to have an exponential distribution with the average amount of time equal to four minutes. X is a continuous random variable since time is measured. It is given that μ = 4 minutes. To do any calculations, you must know m, the decay parameter. m = 1 μ. Therefore, m = 1 4 = 0.25. WebOct 21, 2024 · Then the binomial can be approximated by the normal distribution with mean μ = n p and standard deviation σ = n p q. Remember that q = 1 − p. In order to get the best approximation, add 0.5 to x or subtract 0.5 from x (use x + 0.5 or x − 0.5 ). The number 0.5 is called the continuity correction factor and is used in the following example. free reserves includesWebBinomial probability distribution A disease is transmitted with a probability of 0.4, each time two indivuals meet.
