The multiple-play strategy. Multiple play is a bundling strategy through which multiple services are provided over a single network. A common triple-play service these days is Internet, television, and telephone. The market for this service has become a key battleground among telecommunication, cable, and broadband service providers. A study compared the pricing (average monthly cost in U.S. dollars) among triple-play providers using DSL, cable, or fiber platforms.13 The following table summarizes the results for 47 providers. Group n x s DSL 19 104.49 26.09 Cable 20 119.98 40.39 Fiber 8 83.87 31.78 (a) Plot the means versus the platform type. Does there appear to be a difference in pricing? (b) Is it reasonable to assume that the variances are equal? Explain. (c) The F statistic is 3.39. Give the degrees of freedom and either an approximate (from a table) or an exact (from software) P-value. What do you conclude?
