Question

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.
62 64 64 55 64 52 61 60 61 70 58 69 O
E Click the icon to view the table of Chi-Square critical values.
The confidence interval estimate is mih <a<Omih.
(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
OB. 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.
