Question

About 2% of the population has a particular genetic mutation. 600 people are randomly selected. find the standard deviation for the number of people with the genetic mutation in such groups of 600. round answer to 4 decimal places.

Answer 1

The standard deviation is 0.4801.

To find the standard deviation we use the formula:

s = √n(p)(1-p), where n is the sample size and p is the probability.

Using this, we have:
s = √600(0.02)(1-0.02) = √600(0.02)(0.98) = 0.4801.
