Listed below are speeds (mi/h) measured from traffic on a busy highway. This random sample was obtained at 3:30PM. On a weekday. Use the sample data to construct an 80% confidence interval estimate of the population standard deviation.
62 61 61 55 61 55 59 58 59 70 58 67
The confidence interval estimate is mi/h
(Round to one decimal place as needed.)
