WebTheorem 7.4 If X n →P X and Y n →P Y and f is continuous, then f(X n,Y n) →P f(X,Y). If X = a and Y = b are constant random variables, then f only needs to be continuous at (a,b). Thus, the sum of the limits equals the limit of the sums, the product of the limits equals the limit of the products, etc. Theorem 7.5 For a constant c, X n WebJan 18, 2024 · P (X ≤ x) = P (X < x) + P (X = x) and since a normal random variable is continuous P (X = x) = 0. Therefore. P (X ≤ x) = P (X < x) in this case. Because of this we can say. P (X < 6) = P (X ≤ 6) = Φ( 6 −4 4) = Φ( 2 4) = Φ(0.5) Then we check our normal distribution tables and see that. P (X < 6) = Φ(0.5) ≈ .6915. Answer link.
WebThe binomial distribution for a random variable X with parameters n and p represents the sum of n independent variables Z which may assume the values 0 or 1. If the probability that each Z variable assumes the value 1 is equal to p, then the mean of each variable is equal to 1*p + 0* (1-p) = p, and the variance is equal to p (1-p).
