Webb3 okt. 2024 · Step 1: Sketch a normal distribution with a mean of μ=30 lbs and a standard deviation of σ = 5 lbs. Step 2: A weight of 35 lbs is one standard deviation above the mean. Add the percentages above that point in the normal distribution. 13.5% + 2.35% + 0.15% = 16%. Step 3: Since there are 200 otters in the colony, 16% of 200 = 0.16 * 200 = 32. WebbYou know Φ(a) and you know that the total area under the standard normal curve is 1 so by mathematical deduction: P(Z > a) is: 1 - Φ(a). P(Z > –a) The probability of P(Z > –a) is …
WebbThe normal distribution is a continuous probability distribution. This has several implications for probability. The total area under the normal curve is equal to 1. And, the probability that a normal random variable X is less than positive infinity is equal to 1; that is, P (X < ∞) = 1. Webb13 sep. 2015 · NormalDist can be used to compute the overlapping coefficient ( OVL) between two normal distributions via the NormalDist.overlap (other) method which returns a value between 0.0 and 1.0 giving the overlapping area for two probability density functions: from statistics import NormalDist NormalDist (mu=2.5, sigma=1).overlap …
