Answer:
Use the value the problem statement tells you. Otherwise, use a better approximation.
Step-by-step explanation:
π ≈ 3.141592653589793238... (a non-repeating infinite decimal)
3.14 = 3.14
22/7 = 3.142857142857_142857
355/113 = 3.14159292035... (a very long repeating decimal)
You can see that the third decimal place is wrong in both of your approximations. The last approximation shown has 7 good decimal digits. A good scientific or graphing calculator will have an internal value for pi that is good to 10 or 12 digits or more (preferably, at least 32 digits).
You should use a value for pi that has at least one more digit of accuracy than the number of significant digits in your answer.

The standard deviation for the number of people with the genetic mutation is 3.77
<h3>How to determine the standard deviation?</h3>
The given parameters are:
Sample size, n = 300
Proportion that has the particular genetic mutation, p = 5%
The standard deviation for the number of people with the genetic mutation is calculated as:
Standard deviation = √np(1 - p)
Substitute the known values in the above equation
Standard deviation = √300 * 5% * (1 - 5%)
Evaluate the product
Standard deviation = √14.25
Evaluate the exponent
Standard deviation = 3.77
Hence, the standard deviation for the number of people with the genetic mutation is 3.77
