The campus at Joliet Junior College has a lake. A student used a Secchi disk to measure the clarity of the lake’s water by lowering the disk into the water and measuring the distance below the water surface at which the disk is no longer visible. The following measurements (in inches) were taken on the lake at various points in time over the course of a year. 826462666843382668565466a. Using the data above, compute a point estimate for the population mean and population standard deviation. b. Construct a 95% confidence interval for the mean Secchi disk measurements. Interpret this interval. c.Construct a 95% confidence interval for the population standard deviation Secchi disk measurements. Interpret this interval.
