The waiting line at Golden Eagle Bank can get fairly long. In a recent study, you checked the length of the line 60 random times during one day. The table below shows the full set of results. (The table shows, for example, that on two of the checks, there was no one in line; on 11 of the checks there was 1 customer in line; etc.)
