etc.

The complete data file is available here.

For this assignment, use SAS to read and label the data.

1. Produce a table of means, standard deviations and sample sizes for the continuous variables.
2. Produce frequency distributions for the categorical variables.
3. Produce a correlation matrix of weight and the length variables.
4. You will turn in hard copy of your log file (not the program file, the log file) and your output file. Make sure your name is written clearly on both files.

Please note that this is not a group project. You must do the work yourself, using an installation of SAS on your computer. Do not copy anyone's code (except mine), or allow yours to be copied. I will enforce this.
