of a weekend investment television program predicted a 50% chance of XYZ stock

3 Discussion 2
Marie claims she can
predict the sex of pregnant women’s babies. She sees 1,000 women a year, and
she always predicts a female. She charges $1,000 for a prediction, and she
always predicts a female (although clients do not know that). When she is
wrong, she offers a double-your-money back guarantee. Since the chance of
having a female is approximately 50%, how can she earn any money?

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 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?

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?
