Use a TI-83/84 Plus calculator to create a random sample of four integers between 2 and 9, inclusive. Solution Press, then scroll over to PRB, choose option 5:randInt( and press. Type 2,9,4 ) and press. You will then have something similar to the screenshot to the right. Example T.1: Using a TI-83/84 Plus Calculator to Generate Random Integers

Example T.1: Using a TI-83/84 Plus Calculator to Generate Random Integers (cont.) This screenshot shows a random sample of 9, 9, 3, and 6. Your random sample will obviously be different. Duplicate numbers are a possibility, as shown in our example. If distinct numbers are required, you might need to increase the number of random digits you ask the calculator to generate.

Example T.2: Using Microsoft Excel to Generate Random Integers Use Microsoft Excel to create a list of five random numbers between 200 and 299, inclusive. Solution In cell A1, type =RANDBETWEEN(200, 299). This will give you one random number. Copy that formula and paste it into four additional cells to get the remaining four random numbers.

Example T.2: Using Microsoft Excel to Generate Random Integers (cont.) Your worksheet might look like the screenshot. In this screenshot, the random numbers are 213, 290, 250, 265, and 261. It is possible for Excel to duplicate random numbers here. If distinct random numbers are required, you will likely need to generate additional numbers.

Example T.3: Using M INITAB to Generate Random Integers Generate 20 random integers between 1 and 100, inclusive, using M INITAB. Solution Go to Calc ► Random Data ► Integer. Enter the following parameters: Number of rows of data to generate: 20; Store in column(s): C1; Minimum value: 1; Maximum value: 100; then click OK. The results will be produced in column C1.
