Hello everyone. Let's take a look at this question together, and it says, presume that everyone who works in the marketing department of a corporation is included in the population. Describe how to obtain a sample of 6 employees so that the result is a simple random sample. Is it answer choice A? Group employees based on job roles and randomly select one from each group. Answer choice B, choose 6 employees who volunteer for the study. Answer choice C, select the 1st 6 employees who arrive at work in the morning, or answer choice D assign each employee a number and use a random number generator to select 6 employees. So in order to solve this question, we have to recall what we have learned about a simple random sample to determine which of the following answer choices is a method that describes how we can obtain a sample. 6 random employees. Well, we know that in a simple random sample, every individual has an equal chance of being selected. So we need to use a method that allows for an equal chance of being selected. Well, we know that the population refers to all of the employees in the marketing department. Therefore, in order to obtain a simple random sample of 6 employees from. All of the employees in the marketing department, what we can do is we can assign each employee a number, such as if there were 50 employees, we would number the employees from 1 to 50, and then we can use a random selection method such as a random number generator to select 6 distinct numbers. As this method ensures that every individual has an equal chance of being selected. Resulting in a simple random sample. So looking at our answer choices, we can identify that answer choice D is the correct answer, as answer choice D, which says assign each employee a number and use a random number generator to select 6 employees, describes how to obtain a sample of 6 employees so that the result is a simple random sample, and all other answer choices are incorrect. I hope you found this video to be helpful. Thank you and goodbye.
