Question

1. which of the following situations would most likely result in an unreliable sample mean? a. a representative sample with no outliers b. a small sample with a single extremely large value c. a large, random sample d. a sample with values close together

Explanation:

A small sample size is more affected by outliers. A single extremely large value in a small sample can skew the sample mean significantly, making it unreliable. In contrast, a representative sample with no outliers, a large - random sample, and a sample with values close together are more likely to give a reliable sample mean.

Answer:

B. A small sample with a single extremely large value
