Scenario

A new product was tested in Fresno, CA with a 25cent coupon, and in Tulsa, OK with a 50cent coupon. A sample of 100 people was contacted in each test city. A total of 40 percent of those contacted in Tulsa had tried the new product, whereas only 30 percent of those contacted in Fresno had tried it, a 10 percent difference. Prior to making the decision as to which coupon to use in the marketing program, a hypothesis was suggested.

1. What should the null hypothesis be for this scenario?
2. What should the alternative hypothesis be for this scenario?
3. The probability of obtaining this result under the null hypothesis, namely, that the trial level in Tulsa was 10 percent higher than that in Fresno, was determined to be 0.06. What is thepvalue?
4. Is the result significant at the .10 level? At the .05 level? Would you reject the null hypothesis at the .10 level? At the .05 level?
5. Does the hypothesis show that there will be more trials with a 50cent coupon? Do you feel that a 50cent coupon should be used?
