Use the given degree of confidence and sample data to find a confidence interval for the population standard deviation. Assume that the population has a normal distribution. The hockey coach selected eight players at random and timed how long each player took to finish their exercises. The times (in minutes) were: 8, 15, 12, 10, 10, 7, 9, and 9. Find a 90 percent confidence interval for the population standard deviation.
