Question
Assume that you have a binomial experiment with p = 0.4 and a sample size of 50. The variance of this distribution isQuestion 8Select one:a.1.44b.144c.12d.20
Solution
The variance of a binomial distribution is calculated using the formula:
Variance = np(1-p)
where: n = sample size p = probability of success
In this case, n = 50 and p = 0.4. Substituting these values into the formula gives:
Variance = 500.4(1-0.4) = 500.40.6 = 12
So, the correct answer is c. 12.
