Example Distribution of Test Scores

13.5%

2.5%

In a class of 200 students, the scores

on a test were normally distributed.

The mean score was 66.5 and the

standard deviation was 6.5. The

number of students who scored greater

than 73 percent was about 13.5% + 2.5% of

those who took the test.

16% of 200 = 32

About 32 students scored 73 or higher

on the test.

Conjunto vacio (p. 195) Conjunto que no tiene

elementos.

Expresion num erica (p. 4) Frase matematica que contiene

numeros y operaciones con simbolos, pero no variables.
