bartleby Fundamentals of Biostatistics Question Q SEARCH Chapter 6, Problem 17P To determine Expert Solution & Answer Find a 95% confidence interval for the percentage of males among patients discharged from Pennsylvania hospitals. Answer to Problem 17P ASK AN EXPERT CHAT VX MATH SOLVER - The 95% confidence interval for the percentage of males among patients discharged from Pennsylvania hospitals is (0.25, 0.63). Explanation of Solution From Exercise 15, the best point estimate for the percentage of males among patients discharged from Pennsylvania hospitals,p is 0.44. From Exercise 15, the standard error of the sample proportion is 0.099. Since the required confidence interval is 95%, the two-tailed z-critical value is 1.96. The 95% confidence interval for the proportion of males among patients discharged from Pennsylvania hospitals is given and calculated as follows: CI = ô ± z.q (SE) 0.44 ± (1.96) (0.099) 0.44 0.19404 = (0.24596, 0.63404) ≈ (0.25, 0.63) Is the number (1.96) If not, how do Thank you! < Previous Chapter 6, Problem 16P BB Next > Chapter 6, Problem 18P SAVE DATE THIS SOLUTION Thus, the 95% confidence interval for the percentage of males among patients discharged from Pennsylvania hospitals is (0.25, 0.63).
