INSTALLATION AND USE INSTRUCTIONS ***************************************** We suggest that you copy all of these materials into a folder on your computer C-drive that is named Tanis-Hogg. Some of the following comments assume that you have done this. The following components are included on this disk: 1) Data. The folder titled "Data" includes the data files for most of the exercises and examples in the text. Each chapter for which data files are given has it's own folder and these folders include separate folders for pertinent sections. The files are saved in a number of different formats to provide maximum flexibility to the user. Minitab files are saved as both .mtp (Minitab Portable) and .mtw (Minitab Worksheet) files. Users of other software packages will be able to import the .txt (ASCII) files. Many of these ASCII data files have a column header. The data have also been stored for use with "R" or other programs for which are data are read in from an ASCII file with no column headers. (See below for further information about use with "R".) These data files use the following naming convention: Example_3_1-01.mtw stands for Example 1 in Section 3.1. This is a Minitab worksheet. The same data saved as a Minitab portable file is named Example_3_1-01.mtp. Exercise_3_1-01.mtw holds the data for Exercise 3.1-1. And Application_3_1-1.mtw holds the data for Application 3.1-1. The respective ASCII files are named Example_3_1-01, Exercise_3_1-01, and Application_3_1-1. The data are also stored by chapters in a format that is suitable for use in Maple programs. The Maple data files are stored as Chapter_02.txt, Chapter_03.txt, Chapter_04, and Chapter_05.txt. You can read the data for an entire chapter into a Maple worksheet using, e.g., the command read `C:\\Tanis-Hogg\\Data\\Chapter_03.txt`: where it is assumed that you have copied these materials into a folder named Tanis-Hogg on your C-drive. Within the Maple worksheet, type X := Example_3_1_1; to see and use the data in Example 3.1-1. Remember that Maple is case sensitive and it is necessary to type this as shown. For exercises that have grouped data, the data are sometimes listed both grouped and ungrouped. For example, L := Exercise_2_4_5G; would list the data in Exercise 2.4-5 as grouped data while X := Exercise_2_4_5; would list the data individually. When more than one data set is needed for an example or exercise, the following convention is used: Exercise_3_3_4A; gives the first set and Exercise_3_3_4B; gives the second set of data in Exercise 3.3-4. The data for use by Maple are stored in .txt files so you can easily see them. In fact, you can copy-and-paste a data set from one of these files into a Maple worksheet. The data have been stored for use with "R" or other programs for which the data are read in from an ASCII file. To minimize the amount of typing needed to obtain a data set, the data for each exercise and for each example are listed separately in the Data folder. They are named, e.g., E3_1-01 for Exercise 3.1-1 and Ex3_1-01 for Example 3.1-1. Each one of these files uses a 2-digit number for the exercise or example number. This was done for consistency. You should be able to open any of these data sets to check it out. Also, there are no column headers for these data. Many of the data sets that compare samples from two distributions are listed in the second column with the first column giving a tag to the data. 2) The folder "Maple Examples" illustrates how you can use Maple in a variety of ways. Many of these examples come from Chapter 5 but other examples come from other parts of the text. The Maple Instructions in a Word document gives additional information about these materials. It also lists the contents of the file Menu.mws, showing what examples and exercises are available. There are more than 130 statistics and probability procedures included in stat.m and modifications of some of those that are saved as .txt files. A short summary description of these procedures is included in a pdf file called MapleCard.pdf. If you print out those six summary pages, you can cut and paste them onto a card that is 8-1/2 inches by 14 inches and use a tri-fold. To use these materials, 1. Open Maple on your computer. 2. Open the "Maple Examples" folder that has been stored on your C-drive in a folder named Tanis-Hogg. 3. Within that folder open the file Menu. 4. There are some Maple commands within the Menu that must be run before the examples are viewed. A challenge is to let Maple know where these files are located. That is why we have suggested that "Maple Examples" should be in the Tanis-Hogg folder on your C-drive. Assuming that is the case, all of the necessary supplementary files will be loaded. For example, read `C:\\Tanis-Hogg\\Maple Examples\\stat.m`: reads in the set of 130 supplementary procedures. 5. After activating those first commands, open any of the sections and by clicking on "Solution" you will be taken to the solution. After viewing the solution, you can "Return to Menu" to see another application. 6. If any of the solutions don't run as expected, repeat the commands above. Note that all of the above are suitable for projecting during a class. If you have any questions or comments, e-mail tanis@hope.edu and Elliot Tanis will respond. Some answers and/or corrections will be shown on http://www.math.hope.edu/tanis/ so check that out from time to time. **************************** IV.
