Graphing data is usually the best way to see patterns in the data and to look for possibleproblems. Because graphs also have their limitations, it's often a good idea to also look at theraw data in the form of a frequency distribution table. The frequency distribution table consistsof the categories you are going to measure (X) and the number or frequency of the individuals orresponses in each category (f).\Frequency DistributionTableFrequency Distribution of Number of ViolationsNo. of customers observed exceeding limit (X) Frequency of occurrence, observation periods (f)518214174.125.6.6 or more C)ln how many observation periods were for or more customers observed exceedingthe item limit?D) In what percentage of the observation periods were two customers observedexceeding the item limit? (Remember: the total number of observation periods was 68)

The frequency distribution of the number of customers exceeding the item limit is given.
