Cybersecurity is an area of increasing concern. The National Security Agency (NSA) monitors the number of hits at sensitive websites. When the number of hits is much larger than normal, there is cause for concern, and further investigation is warranted. For each of the past 12 months, the number of hits at one such website has been 181, 162, 172, 169, 185, 212, 190, 168, 190, 191, 197, and 204. Determine the upper and lower control limits (99.7%) for the associated c-chart. Using the upper control limit as your reference, at what point should the NSA take action?
