The National Assessment of Educational Progress (NAEP) includes a mathematics test for eighth-grade students. Scores on the test range from 0 to 500.

An example of the knowledge and skills associated with the Proficient level is being able to read and interpret a stem-and-leaf plot. In 2019, 147,400 eighth-graders were in the NAEP sample for the mathematics test. The mean mathematics score was x = 282. We want to estimate the mean score u in the population of all eighth-graders.
