Bergen County's Department of Tourism and Recreation collects data on the number of visitor cars with NY license plates in one of its parks. (The group's position is that more out-of-state plates mean the advertising programs are working, that is, they meet quality expectations). The sample size is fixed at n=30 each day. Data from the previous 10 days indicate the following number of NY license plates:

Day	1	2	3	4	5	6	7	8	9	10
Number	5	7	8	3	6	9	4	5	10	3

1. What type of Statistical process Control Charts is appropriate in this case?

2. What is the expected value of the variable of interest in this situation?

3. What are the 99.73% UCL and LCL for these data?

4. If a new sample of 15 cars is taken in day 7 and 8 cars are "out of state", what can you conclude from this information?
