A regional retail corporate team is contemplating a decision to purchase an automated customer service system. The mean cost of a phone call handled by an automated menu customer service system is $0.75 while the mean cost of a phone call passed onto a “live” operator is $7.00. However, empirical data show that as more and more companies have implemented automated systems, customer annoyance with such systems has grown substantially. Many customers are quick to leave the automated system when given an option. According to the Center for Marketing Research, 40% of all callers to automated customer service systems automatically opt to go to a live operator when given a chance. What if the number of debilitating network viruses detected in a day at the firewalls of an Internet Service Provider within a certain geographic region is fueling a possible management decision to upgrade the detection system. The decision will be based on the results of the following data analysis. The mean number of network viruses detected in a day is 3.0. What is the probability that in any given day: e. Zero network viruses will be detected? f. Exactly one network virus will be detected? g. Two or more network viruses will be detected? h. Fewer than three network viruses will be detected?
