An experiment was conducted to investigate the precision of measurements of a saturated solution of iodine after an extended period of continuous stirring. The data shown in the table represent  n = 10 iodine concentration measurements on the same solution. The population variance σ² measures the variability—i.e., the precision—of a measurement. Find a 95% confidence interval for σ². Interpret the result.
