DVD users

BUS 352 Grand Canyon Module 8 Discussion 1

A market researcher is interested in knowing the type of training that works best for DVD users. Thirty consumers are randomly selected from a population of known DVD owners (i.e., users). Ten users are trained by giving them the DVD user’s manual and allowing them to read it. Another 10 users are trained from a 30 minute DVD user training video. Another 10 users are trained from a self-paced computer tutorial. The users are then timed in their ability to setup and program the DVD by performing a series of operations. Which statistical analysis technique should be used? What is the null hypothesis? Can the market researcher get an answer? Why or why not?

Your client wants to know if the data set represents a normal distribution. Which statistical analysis technique should be used? What is the null hypothesis? Can an analysis be performed? Why or why not?
