Which of the following is a simulation?

1. measuring the mean and standard deviation of measurement from a sample

2. taking a series of measurements based on multiple samples

3. some method of generating virtual measurements that look like what would be gotten from a sample

4. specifying the expected mean and standard variation of measurements for an entire population

Option: 3 is the correct answer.

3.   Some method of generating virtual measurements that look like what would be gotten from a sample

Simulation Technique--

A simulation technique  is a process of using  probability experiment in order to model the random events closely the real world outcomes or real life situations. The process is also known as mathematical modeling.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
