Chapter 7, Problem 7.5-3(choose chapter or problem)
A sample of n = 9 electrochromic mirrors was used to measure the following low-end reflectivity percentages:
7.12 7.22 6.78 6.31 5.99 6.58 7.80 7.40 7.05
(a) Find the endpoints for an approximate 95% confidence interval for the median, m.
(b) The interval \((y_3, y_7)\) could serve as a confidence interval for m. Find it and give its confidence coefficient.
