Could you tell me how to figure pout this problem using stat crunch?

Your daily commute to work requires that you cross railroad tracks. At this particular railroad crossing the trains tend to be long and slow.So, getting stopped by a train will likely make you late for work. You start recording data to determine the likelihood of arriving at the tracks while a train is there. The data contain the day number and whether a train waspresent, ornot, for 200 consecutive days in which you drove to work. In the dataset, the column Train shows a series of 0s and 1s. In that column a 0 indicates there was no train present and a 1 indicates that a train was present. The column Aggregate Train represents the cumulative number of times a train was present.

(a) Consider the first 10 days of data. For this timeperiod, what proportion of days had a trainpresent?

There is a data table that comes with it that's goes into stat crunch, but from there I'm not sure what to do.

Thank you!
