3.34 Body Mass Index. Your body mass index (BMI) is your weight in kilogramsdivided by the square of your height in meters. Many online BMI calculators allowyou to enter weight in pounds and height in inches. High BMI is a common butcontroversial indicator of overweight or obesity. A study by the National Center forHealth Statistics found that the BMI of 2-year-old American male children isapproximately Normally distributed, with mean 16.8 and standard deviation 1.9.2a. What percentage of 2-year-old American male children have a BMI less than15.0?b. What percentage of 2-year-old American male children have a BMI less than18.5?

The National Assessment of Educational Progress (NAEP) includes a mathematics test for eighth-grade students. Scores on the test range from 0 to 500. Demonstrating the ability to use the mean to solve a problem is an example of the skills and knowledge associated with performance at the Basic level. 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.
