If the standard deviation of a Poisson variate X is 2, what is P (1.5 < X < 2.9) |
|
Answer» Answer: Step-by-step EXPLANATION: Since Poisson distribution is a discrete distribution, therefore it TAKES discrete values of 0, 1, 2, 3,4, and 5 Therefore, 1.5 < X < 2.9 means X takes value 2 . HENCE P(1.5 < X < 2.9) = P(X = 2) = e^(-4)(4)^(2)/2! |
