Question

The Coca-Cola Company introduced New Coke in 1985. Within three months of this introduction, negative consumer reaction forced Coca-Cola to reintroduce the original formula of Coke as Coca-Cola Classic. Suppose that two years later, in 1987, a marketing research firm in Chicago compared the sales of Coca-Cola Classic, New Coke, and Pepsi in public building vending machines. To do this, the marketing research firm randomly selected 10 public buildings in Chicago having both a Coke machine (selling Coke Classic and New Coke) and a Pepsi machine. The researchers recorded the number of cans sold over a given period of time. What is the null hypothesis for this study?

Answer 1

Explanation:

The question requires us to state the null hypothesis only.

A null hypothesis can be used in statistics or experimental research to show that there is no difference in existence between the populations that were specified for the study. An alternative hypothesis is the opposite as it proposes the existence of a difference.

Here is the null hypothesis:-

H0: there are no differences existing between the mean sales of coca-cola classic, coke and pepsi in public vending machine.
