A home theater in a box is the easiest and cheapest way to
provide surround sound for a home entertainment center. A sample of
prices is shown here (Consumer Reports Buying Guide,
2004). The prices are for models with a DVD player and for models
with a DVD player.
- Compute the mean price for models with a DVD player and the
mean price for models without a DVD player. What is the additional
price paid to have a DVD player included in a home theater
unit?
- Compute the range, variance, and standard deviation for the two
samples. What does this information tell you about the prices for
models with and without a DVD player?
