Question

AMS communicates with customers who sub-scribe to cable television services through a special se-cured email system that sends messages about service changes, new features, and billing information to in-home digital set- top boxes for later display.
1. Analyze the data in Table AMS10.1 and write a report to the computer operations department that indicates your findings. Include an appendix in which you discuss the reason you selected a particular statistical test to compare the two independent groups of callers.
2. Suppose that instead of the research design described in the case, there were only 15 subscribers sampled, and the update process for each subscriber email was measured for each of the two messaging systems. Suppose that the results were organized in Table AMS10.1— making each row in the table a pair of values for an individual subscriber. Using these suppositions, reanalyze the Table AMS10.1 data and write a report for presentation to the team that indicates your findings.
3. Analyze the data in Table AMS10.2 and write a report to the computer operations department that indicates your findings. Include an appendix in which you discuss the reason you selected a particular statistical test to compare the three email interfaces.
