He decides to repeat the experiment using a larger sample size.Options:  a. a sample size of 300 peopleb. research on the medical historyc. collects the information using reliable sourcesd.Repeat the experiment using a larger sample size

Answer 1

The answer is:

A - A sample size of 300 people.

This is because it shows how he has limited resources and he cannot use more people because of his limitations.

Answer 2

The correct answer is option a. a sample size of 300 people.

In this case, there are 200,000 people who are already taking the drug, and the scientist take only 300 people for the experiment. The sample size of 300 is very small as compared to 200,000. Including 300 people only would not give any effective result, or may be all the possible outcomes are not included in the result, so, this can be the limiting factor to the experiment.
