Question

Suppose a random variable, x, arises from a binomial experiment. If n = 14, and p = 0.13, find the standard deviation. Round answer to 4 decimal places.

Answer 1

Answer:

The standard deviation is 1.2583

Step-by-step explanation:

We are given the following information in the question:

Sample size, n = 14

p = 0.13

We have to find the standard deviation.

Formula:

$\text{Standard deviation} = \sqrt{n\times p\times (1-p)}$

Putting the values, we get,

$\text{S.D} = \sqrt{14\times 0.13\times (1-0.13)} = 1.2583$

The standard deviation is 1.2583
