Question

Assume that a procedure yields a binomial distribution with “n” trials and the probability of success for one trial is “p”. Use the given values of “n” and “p” to find the mean μ and standard deviation σ. Also, use the range rule of thumb to find the minimum usual value μ + 2 σ.
n = 100, p = 0.8

Answer 1

The mean is given by:
\[\large \mu=np\]
The standard deviation is given by:
\[\large \sigma=\sqrt{np(1-p)}\]

Answer 2

Thank you!
