This is a word question that confuses me. I picked the wrong answer. Upon review, I think it would make sense to write names of all 40 employees then mix up and pick 10 out. Is that the more mathematically correct way to conduct the study? (see question 1 below)

Muriel is conducting research for a study about the work habits of employees in an office. She collects data by interviewing employees out of a total of 40 employees that work in the office. What sampling method would provide her the most representative sample? O Muriel interviews the 10 employees she thinks would be the most likely to volunteer to be interviewed. O Muriel interviews the 10 employees who were most recently hired. Muriel writes down the names of all 40 employees on individual pieces of paper. She then folds the pieces of paper up, places them in a bowl, and shakes the bowl around to mix up the pieces of paper. She then draws 10 pieces of paper out of the bowl and interviews the employees that have their names on those tickets. 6 Muriel emails all 40 of the employees and asks for volunteers. She then interviews the first 10 volunteers
