Two major computer companies manufacture and sell computer accessories. The prices of 5 randomly selected accessories are listed below:

Computer Accessory Price Data
Computer Accessory Macrohard Price ($) Pear Computer Price ($)
keyboard 75.29 56.12
mouse 51.69 46.83
speaker 114.37 107.23
modem 107.50 107.07
monitor 443.99 419.84

The quality of the computer accessories for both companies are practically the same because both companies purchase the parts from the same wholesaler. Since the market for these accessories is very competitive, the main reason why one product would be more expensive than another would be due to brand name and the advertizing related to it.

H0: Macrohard accessories are equal in price to or cheaper than Pear Computer productsHa: Macrohard accessories are more expensive
