13. Crash Test Results The following data represent the repair cost for a low-impact collision in a simple random sample of mini- and micro-vehicles (such as the Chevrolet Aveo or Mini Cooper). In Problem 33 from Section 9.2, it was verified that the data come from a population that is normally distributed with no outliers and s = $1007.4542. Construct and interpret a 90% confidence interval for the standard deviation repair cost of a low-impact collision involving mini- and micro-vehicles. $3148 $1758 $1071 $3345 $743 $2057 $663 $2637 $773 $1370 Source: Insurance Institute for Highway Safety
