1. We trained rats to run a straightalley maze for food reinforcement. All of a sudden one of the rats laid down and went to sleep halfway through the maze.

2. If you have access to SPSS, go to the Web site for this book.
Select the link for the short SPSS manual and read the introduction. Download the "apgar.sav" file referenced there and open it in SPSS. To download the file, right click on the file name and select a location to store it. After you have done that, double click on the icon for that file and it will open in SPSS. What can you tell about the data? How would you describe the scale of measurement of the 10 variables given there?
