Final answer:
The number of members surveyed that could result in a sample statistic but not a parameter is 400.
Step-by-step explanation:
In this question, we are asked to determine which numbers of members of the population surveyed could result in a sample statistic but not a parameter. A parameter is a value that describes a population, while a sample statistic is a value that describes a sample.
Out of the given options, the number of members surveyed that could result in a sample statistic but not a parameter is 400 (option D). This is because 400 is a smaller subset of the population and represents a sample, while 40,000 represents the entire population and is a parameter.
