A city wants to estimate the standard deviation of the time it
takes a bus to travel between two stops in a city. To develop an
estimate for the standard​ deviation, the city has collected a
random sample of the times required for 19 trips. The sample
standard deviation is 5.5 minutes. Based on these​ data, what
is the 95​% confidence interval estimate for the true population
standard deviation.
____________ minutes ≤σ≤ ____________ minutes
