QUESTION
If x is a binomial random variable, calculate ,2 ,and for each of the following values of n and p. Complete parts a through f. n=25 ,p=0.
If x is a binomial random variable, calculate μ ,σ2 ,and σ for each of the following values of n and p. Complete parts a through f.
a. n=25 ,p=0.5
n = 25, p = 0.5Expected value of X, Mean = µ = np = 25 ∗ 0.5 = 12.5Expectation or mean is: µ = 12.5Variance: σ 2 = np(1 − p) = 25 ∗ (0.5)(1 − 0.5) = 6.25Variance: σ 2 = 6.25Std...
