Chapter 4.1, Problem 9GA

The probability of a package of Oreos containing between 514 and 522 grams can be written as $P\left(514<x<522\right)$, where x represents the weight. This uses a compound inequality, which is a combination of two inequalities. In this case, $514<x<522$

means that x is both greater than 514 (that’s the $514<x$

part) AND less than 522 (which is the $x<522$

part). In other words, x is between 514 and 522.

Find the probability described in Question 8. (This will require some interpretation of the diagram illustrating the empirical rule.)
