A quality control manager wants to see how many defective products come off the line on average per day. They use a random number generator to select 100 of the 1500 units produced that day and tested whether they were defective. What type of sampling method is this?

Welcome back. For this problem, we have the quality control manager who wants to see how many defective products come off the line on average per day. They use a random number generator to select 100 of the 1,500 units produced that day and tested whether they were defective. We wanna know what type of sampling method is this. We see a random number generator picking random units from all of the units produced in the day, so we see a large pool containing all possible members of the population that we are selecting from at random. The random number generator also means that each unit has the same chance of being selected, so this is an example of an SRS or a simple random sample. Great work.
