Listed below are speeds (mi/h) measured from traffic on a busy highway. This simple random sample was obtained at3:30 P.M. on a weekday. Use the sample data to construct a 98% confidence interval estimate of the population standard deviation. A. The confidence interval estimate is mi/hless than sigma less than mi/h. (Round to one decimal place as needed.)
