@8141 For the provided sample mean. sample size. and population standard deviation. complete parts (a) through (c) below. i=3o. n=1oo, =2 a. Find a 95% condence interval for the population mean. The 95% condence interval is from 29.61 to 30.39 . (Round to two decimal places as needed.) b. Identify and interpret the margin of error. The margin of error is 0.39 . (Round to two decimal places as needed.) Interpret the margin of error. Choose the correct answer below. f. A. We can be 95% condent that any possible value of the variable is within the margin of error of the sample mean, 30. v * B. We can be 95% condent that the population mean, u. is within the margin of error of the sample mean, 30. @x C, We can be 95% condent that any possible sample mean is within the margin of error of 30. v f D. We can be 95% condent that any possible value of the variable is w'r1in the margin of error of the population mean. u. c. Express the endpoints of the condence interval in terms of the point estimate and the margin of error. The 95% condence interval is D 1 |:|. (Round to two decimal places as needed.) According to a study of political prisoners, the mean duration of imprisonment for 34 prisoners with chronic post-traumatic stress disorder (PTSD) was 34.7 months. Assuming that o = 35 months, determin your answer in words. Click here to view Page 1 of the table of areas under the standard normal curve. Click here to view Page 2 of the table of areas under the standard normal curve. A 95% confidence interval for the population mean is from 22.9 months to 46.5 months. (Round to one decimal place as needed.) Interpret the confidence interval. Select the correct choice below and fill in the answer boxes to complete your choice. Round to one decimal place as needed.) O A. There is a 95% chance the mean duration of imprisonment, u. of all political prisoners with chronic PTSD will equal the mean of the interval from months to months
