A research team conducted a study of soft- drink preferences among residents in a test market prior to an advertising campaign for a new cola product. Of the participants, 130 are teenagers and 130 are adults. The researchers secured the following results:

Soft-drink…………..Cola…………..Non-cola
Teenagers………….50………………..80
Adults………………..90………………..40

-Perform a chi-squaretest by applying the 6 steps in of research hypothesis testing.

Step 2:
Step 3:
Step 4:
Step 5:

-Interpret the results in layman’s terms that a non-statistician would understand.
-How might the results obtained from the test affect the advertising strategy?

Step 2:
Null hypothesis: there is no association between age (adults versus teenagers) and …

The graphs and rationales for research teams are examined.
