Answer to Question 1

A Z-test for differences of proportions is a technique used to test the hypothesis that proportions are significantly different for two independent samples or groups. The null hypothesis is 1 = 2, which may be restated as 1 - 2 = 0.

Answer to Question 2

Some positioning statements are a bit surprising. For example, Volvo is known for safety, yet at Volvo.com you'll see: We offer transport solutions to demanding customers around the world.. Perhaps Volvo's dominance on safety is so well known that the benefit doesn't need stating. Some positioning statements are straightforward, such as Sam's Club's Savings Made Simple or Walmart's Save money. Live better.. Others are more abstract and inspiring, such as Lowe's Let's Build Something Together, Porsche's Engineered for magic. Every day, or American Cancer Society's The Official Sponsor of Birthdays..
