BUAL 2600 – Section 6 (8:00 am)
Class Exercise 14
Show all of your work.
Scientists working for a major drug company have developed a new antibiotic called Phe-Mycin. The company wishes to estimate p, the proportion of all patients who would experience nausea as a side effect when being treated with Phe-Mycin. Suppose that a sample of 200 patients is randomly selected. When these patients were treated with Phe-Mycin, 35 experienced nausea.
1. What is the sample estimate of the proportion (p?)? (1 point)
2. Show whether the study meets the success/failure condition. (2 points)
3. Calculate the SE(p?). (2 points)
4. Calculate a 95 percent confidence interval. (3 points)
5. Suppose the drug company wishes to find the size of the random sample that is needed in order to obtain a 2 percent margin of error with 95 percent confidence. (2 points)
