Question
Businesses such as General Mills, Kellogg's, and Betty Crocker regularly use coupons to build brand allegiance and stimulate sales.
Marketers believe that the users of paper coupons are different from the users of e-coupons accessed through the Internet. One
survey recorded the age of each person who redeemed a coupon along with the type of coupon (elther paper or electronic). The
sample of 21 traditional paper-coupon clippers had a mean age of 42.1 with a standard deviation of 5.6. The sample of 35 e-coupon
users had a mean age of 36.7 years with a standard deviation of 9.5. Assume the population standard deviations are not the same.
Using a significance level of 0.01, test the hypothesis of no difference in the mean ages of the two groups of coupon clients. Hint. For
the calculations, assume e-coupon as the first sample.
Required:
a. What are the null and alternate hypotheses?
O Ho: Pe-coupon = Htraditional H₁: He-coupon # traditional
O Ho: He-coupon # traditional H₁: He-coupon
traditional
O Ho: Pe-coupon #Ptraditional H₁: He-coupon * Ptraditional
b. Compute the test statistic. (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.)
Test statistic
c. Compute the p-value. NOTE: P-value calculators are available through online search. (Round your answer to 4 decimal places.)
p-value
d. What is your decision regarding the null hypothesis?
O Reject the He
O Fall to reject the He
e. Interpret the result.
