Let's say that you work for a publication and would like to start your first pilot study. Your boss is willing to accept a margin of error of 4% but wants a 95% confidence interval. Notice that the intent of this question is to eventually calculate the required sample size. 6. What is the point estimate, p, that you should use for determining sample size? Notice this is a pilot study. a. 0.05 b. 0.04 c. 0.08 d. 0.5 e. 0.95 7. What is the total width of the confidence interval going to be when it is calculated? a. 0.02 b. 0.04 c. 0.05 d. 0.5 e. 0.08 8. What is the sample size you should use? (Use 1.96 for za/2) 151 b. 600 C. 600.25 d. 601 Use the following 95% confidence interval to answer the following questions: (0.70, 0.80) 9.
