Final answer:
Using a substitution generator on calculators like the TI-83+ and TI-84 involves generating random numbers or applying step-by-step arithmetic operations to create a set of values from a number range. These can be used to select random items or simulate statistics.
Step-by-step explanation:
A substitution generator can be used to create a range of numbers by replacing certain elements with other values. When applied to a number range using a calculator like the TI-83+, TI-84, or related models, the process typically involves generating random numbers that can be used for various purposes, such as selecting items or people from a set.
Solution A details a step-by-step procedure that may involve manually entering a sequence into the calculator, then using arithmetic operations to alter these numbers into the desired range or using them as stand-ins for other values. In contrast, Solution B refers to using built-in functions on calculators such as the TI-83+ and TI-84 to generate random numbers more efficiently.
One common use of these generators, as highlighted in the example provided, is to select items randomly. For instance, Lisa uses her calculator to generate random numbers, such as .94360, .99832, and so on, which are then interpreted in groups of two digits to select class members.
These calculators provide functions that can quickly generate a set of random numbers to be used for selection purposes or to simulate randomness in statistical sampling.
