TECHNOLOGY EXCEL MINITAB TI-84 PLUS 36 CHAPTER 1 Introduction to Statistics Using Technology in Statistics With large data sets, you will find that calculators or computer software programs can help perform calculations and create graphics. These calculations can be performed on many calculators and statistical software programs, such as Minitab, Excel, and the TI-84 Plus. The following example shows a sample generated by each of these three technologies to generate a list of random numbers. This list of random numbers can be used to select sample members or perform simulations. Generating a List of Random Numbers A quality control department inspects a random sample of 15 of the 167 cars that are assembled at an auto plant. How should the cars be chosen? SOLUTION One way to choose the sample is to first number the cars from 1 to 167. Then you can use technology to form a list of random numbers from 1 to 167. Each of the technology tools shown requires different steps to generate the list. Each, however, does require that you identify the minimum value as 1 and the maximum value as 167. Check your user’s manual for specific instructions.
