The median for a random variable X is m such that P ( X ≤ m) ≥ 1 / 2 and P ( X ≥ m) ≥ 1 / 2. In the first example the correct answer is 0: P ( X ≤ 0) = P ( X = 0) = 0.728303 and P ( X ≥ 0) = 1. In the second example it is 2: P ( X ≤ 2) = 0.10 + 0.20 + 0.30 = 0.6, P ( X ≥ 2) = 0.30 + 0.25 + 0.15 = 0.7. Your method is ...

WebWhen a population reaches a high density, there are more individuals trying to use the same quantity of resources. This can lead to competition for food, water, shelter, mates, light, and other resources needed for survival and reproduction. 1. ^1 1. start superscript, 1, end superscript. Predation. Higher-density populations may attract ... WebThe formula for the exponential distribution: P (X = x) = m e-m x = 1 μ e-1 μ x P (X = x) = m e-m x = 1 μ e-1 μ x Where m = the rate parameter, or μ = average time between occurrences. We see that the exponential is the cousin of the Poisson distribution and they are linked through this formula.
