Extracted text: As part of a water quality survey, you test the water hardness in several randomly selected streams. The results are shown below. Construct a confidence interval for the population variance of and the population standard deviation o. Use a 99% level of confidence. Assume that the population has a normal distribution. n = 16 s= 15 grains per gallon ..... What is the confidence interval for the population variance o2? 10.14,27.08) (Round to one decimal place as needed.) Inco
