Listed below are speeds (mi/h) measured from traffic on a busy highway. This simple random sample was obtained at 3:30 P.M. on a weekday. Use the sample data to construct a 99% confidence interval estimate of the population standard deviation. 64 63 63 57 63 52 59 58 59 70 61 67 D Click the icon to view the table of Chi-Square critical values. The confidence interval estimate is mi/h <o< mi/h. (Round to one decimal place as needed.) Does the confidence interval describe the standard deviation for all times during the week? Choose the correct answer below. O A. Yes. The confidence interval describes the standard deviation for all times during the week. O B. No. The confidence interval is an estimate of the standard deviation of the population of speeds at 3:30 on a weekday, not other times.
