In general, the larger a sample is: a. The more difficult it becomes to avoid atypical cases. b. The greater the standard deviation becomes. c. The smaller the standard deviation becomes. d. The more closely it represents the population. e. The more likely it is that it will be biased.

d

Step-by-step explanation:

Think of the difference between sampling hundreds of people from a town, perhaps asking them if they've ever ordered fast food.  If you go to McDonald's and ask customers as they come out, you wouldn't expect those answers to represent the entire population of the town, right?
