The manager of a computer network has collected data on the number of times that service has been
interrupted on each day over the past 500 days. The results are as follows as shown in the table.
Does this distribution of service interruptions follow the expected percentages which are 0=30%, 1=30%,
2= 20%, 3=12%, 4=3%, 5=3%, and 6=2%? Use the 0.01 level of significance.
