Does the confidence interval describe the standard deviation for all times during the week? Choose the correct answer below.

A. 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.

B. Yes. The confidence interval describes the standard deviation for all times during the week.

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 95% confidence interval estimate of
the population standard deviation.
