A direct mail appeal for contributions from a university’s alumni and supporters is considered to be too costly if less than 13% of the alumni and supporters provide monetary contributions. To determine if a direct mail appeal is cost effective, the fundraising director sends the direct mail brochures to a simple random sample of 204 people on the alumni and supporters mailing lists. They receive monetary contributions from 19 people. Does this evidence demonstrate that the direct mail campaign is not cost effective? Use a 0.02 level of significance. Step 3 of 3 : Draw a conclusion and interpret the decision. A. We reject the null hypothesis and conclude that there is suficient evidence at 0.02 level of significance that the direct mail campaign is not cost effective. B. We fail to reject the null hypothesis and conclude that there is suficient evidence at 0.02 level of significance that the direct mail campaign is not cost effective. C. We fail to reject the null hypothesis and conclude that there is insuficient evidence at 0.02 level of significance that the direct mail campaign is not cost effective. D. We reject the null hypothesis and conclude that there is insuficient evidence at 0.02 level of significance that the direct mail campaign is not cost effective.
