If the sample size is 300 and about 5% of the population has a particular genetic mutation then the standard deviation for the number of people with the genetic mutation in such groups of 300 is 3.77.
Given sample size be 300 and about 5% of the population has a particular genetic mutation.
We are required to find the standard deviation for the number of people with the genetic mutation in groups of 300.
Sample size=300
The standard deviation for the number of people with the genetic mutation is calculated as:
Standard deviation=![\sqrt{np(1-p)}](https://tex.z-dn.net/?f=%5Csqrt%7Bnp%281-p%29%7D)
Use the known values in the above formula.
Standard deviation=![\sqrt{300*0.05(1-0.05)}](https://tex.z-dn.net/?f=%5Csqrt%7B300%2A0.05%281-0.05%29%7D)
=![\sqrt{14.25}](https://tex.z-dn.net/?f=%5Csqrt%7B14.25%7D)
=3.77
Hence if the sample size is 300 and about 5% of the population has a particular genetic mutation then the standard deviation for the number of people with the genetic mutation in such groups of 300 is 3.77.
