I was attempting a question where the dataset was paired dataset about time taken by patients to fall asleep before and after taking a sleeping pill. I used the procedure proc ttest to do a hypothesis testing on the data. But it is required to use a 90% Confidence Interval and by default in SAS, it is 95%. So, how can I change the CI to 90%?
Thanks in advance.
