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 ten users are trained from a 30 minute DVD user training
video. Another ten 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?
