Spring 2008 Lab Assignments for Cornell University Math 171

During the academic year, Math 1710 classes meet three times a week for a 50 minute class and once a week for a 50 minute lab. Below are the lab assignments from last Spring. We will ask you this Summer to look at many of them as well as to hand in several of the more interesting ones.

Please understand that the lab time is for doing the software part of the assignment. You should work together to create the graphs, run the stats analysis, etc, cutting and pasting results into a layout or Word document. You can print the layout or create a pdf and email any files to yourself or put them on a USB flash drive. Later on at home you can write up your answers to the rest of the questions individually to be handed in. Answers may be handwritten directly on a printout of your layout if convenient.

Caution:

• When you save a file to your removable media and especially when you go to attach to an eMail, be sure the file is closed!
• Safest is to Quit and Save from DataDesk, your word processor, or your PDF reader then work with the file.
• Sad stories abound of people who sent themselves an eMail with an attachment having 0 Bytes because the file was open when they sent the eMail.

  • DataDeskHelper.dmg: DataDeskHelper for Mac OS X A small utility to simplify getting .dsk downloads to be properly recognized under Mac OS X. Download the Disk Image file and mount it. You can drag files onto the application in the disk image or copy the application to a place you can conveniently drag .dsk files onto it.
  • On Intel Macs results from random number generation with the default random number generator Linear Congruential have at times been useless. Instead, you can use ULTRA or Mother of All RNG from the pop-up menu near the bottom of the dialog.
