Creating a dataset

Hello, I was given this question:

(dataset: SASHELP.BWEIGHT) Create a dataset including first 2,000 observations only in SASHELP.BWEIGHT and report the p-value of testing if two variables MomSmoke and VISIT are independent. Note that you should determine if Chi-sq test is valid or not. Up to four decimal places, please. (Hint: use PROC FREQ)

I understand how to calculate the p-value if the two variables are independent, I am just confused on making a new dataset including the first 2,000 observations of sashelp.bweight.

data want;
set have (obs=2000);

Use the OBS= Dataset option.

The first SAS e-course is free and covers a lot of the questions you've been asking. It may be worth taking sometime to go over the course materials.
