Does Including a Gift with a Request for a Donation

question 27

Multiple Choice

Does including a gift with a request for a donation influence the proportion who will make a donation? This question was investigated in a recent study. Letters were sent to a large number of potential donors in Japan. The letter requested a donation for funding schools in Mali. The letter recipients were assigned at random to one of three groups. Those in the first group received a letter with no gift. Those in the second group received a letter that included a small gift (a postcard) , and those in the third group received a letter with a larger gift (four postcards) . The response of interest was whether or not the letter resulted in a donation. We wish to perform a hypothesis test to determine if there is convincing evidence that the proportions for the two donation categories are not the same for all three types of requests.What is the value of the test statistic for this test?

• A)12.388
• B)5.207
• C)9.502
• D)11.411
• E)14.141
