For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding. Case studies showed that out of 10,001 convicts who escaped from certain prisons, only 7582 were recaptured. (a) Let p represent the proportion of all escaped convicts who will eventually be recaptured. Find a point estimate for p. (Round your answer to four decimal places.) (b) Find a 99% confidence interval for p. (Round your answers to three decimal places.) lower limit upper limit Give a brief statement of the meaning of the confidence interval. We are 1% confident that the true proportion of recaptured escaped convicts falls within this interval. We are 1% confident that the true proportion of recaptured escaped convicts falls above this interval. We are 99% confident that the true proportion of recaptured escaped convicts falls outside this interval. We are 99% confident that the true proportion of recaptured escaped convicts falls within this interval. (c) Is use of the normal approximation to the binomial justified in this problem? Explain. No; np < 5 and nq > 5. No; np > 5 and nq < 5. Yes; np > 5 and nq > 5. Yes; np < 5 and nq < 5.
