Chris P. Bacon is the newly hired Director of Development at Nunya Business College. She hopes that her new lirect mail campaign for alumni donations will get more than 15% of the alumni to donate money to their alma mater. She decides to test the new campaign using a 5% significance level. She selected a random sample of 200 alumni, 38 alumni contributed money to the college. Research Question: Is there sufficient evidence to upport the idea that the new direct mail campaign will yield more than a 15% response rate? What test statistic should you use and why? (There are three basic one-sample hypothesis tests: 1) z-test for the population mean, 2) z-test for the population proportion, and 3) t-test for the population mean.) Based on the research question is this a left-tailed, two-tailed, or right-tailed test?

**Step 1. Test Set-up**

Chris P. Bacon is the newly hired Director of Development at Nunya Business College. She hopes that her new direct mail campaign for alumni donations will get **more than 15%** of the alumni to donate money to their alma mater.

She decides to test the new campaign using a 5% significance level. She selected a random sample of 200 alumni, 38 alumni contributed money to the college. **Research Question:** Is there sufficient evidence to support the idea that the new direct mail campaign will yield more than a 15% response rate?

**What test statistic should you use and why?** (There are three basic one-sample hypothesis tests:  
1) z-test for the population mean, 2) z-test for the population proportion, and 3) t-test for the population mean.)
