Module 8 DQ 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 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?
Why or why not?Module 8 DQ 2
A client gives you a data set of 30 observed
values that represent the number of gallons of gas that 30 individual Nissan
Sentra owners purchased at the gas pump last month. 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?SYM-506 | Additional
