Question:
- AMS communicates with customers who subscribe to cable television services through a special secured email system that sends messages about service changes, new features, and billing information to in-home digital set-top boxes for later display. To enhance customer service, the operations department established the business objective of reducing the amount of time to fully update each subscriber’s set of messages. The department selected two candidate messaging systems and conducted an experiment in which 15 randomly chosen cable subscribers were sampled. The update process for each subscriber email was measured for each of the two messaging systems.
Is there a difference in these two messaging systems? Conduct the appropriate test and analyze the results . Use excel.
