On a portion of the M4 motorway all four lanes in each direction become congested during peak time weekday periods. A study was undertaken to find out if drivers prefer to drive on the inside lanes. A total of 1000 cars were observed during a morning peak period and their respective lanes recorded. It is suspected that each lane has equal preference. Do the data present sufficient evidence that some lanes are preferred over others?
