Question

One survey recorded the age of each person who redeemed a coupon, along with the type of coupon (paper or electronic). The sample of 27 traditional paper coupon users had a mean age of 32.8 with a standard deviation of 9.0. The sample of 35 e-coupon users had a mean age of 38.5 years with a standard deviation of 7.1. Assume the population standard deviations are not the same.

Using a significance level of 0.02, 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.

Find the degrees of freedom for unequal variance test (round down answer to the nearest whole number)
State the decision rule for 0.02 significance level (round your answers to 3 decimal places)
Compute the value of the test statistic (round your answer to 2 decimal places)
