K Use technology to construct the confidence intervals for the population variance of and the population standard deviation o. Assume the sample is taken from a normally distributed population. C=0.98, $2 = 24.01, n=26K The number of hours of reserve capacity of 10 randomly selected 1.71 1.81 1.51 1.62 1.72 automotive batteries is shown to the right. 1.93 1.39 1.53 1.48 2.02 Assume the sample is taken from a normally distributed population. Construct 95% confidence intervals for (a) the population variance of and (b) the population standard deviation o.The diameters (in inches) of 17 randomly selected bolts produced by a machine are listed. Use a 95% level of K confidence to construct a confidence interval for (a) the population variance of and (b) the population standard deviation o. Interpret the results. 4.477 4 424 4.021 4.344 4.003 3.795 3.813 3.746 4.235 3.933 4.121 4.558 3.961 3.756 3.854 3.809 4 432As part of a water quality survey, you test the water hardness in several randomly selected streams. The results are K shown below. Construct a confidence interval for the population variance of and the population standard deviation o. Use a 90% level of confidence. Assume that the population has a normal distribution. n = 21 s = 14 grains per gallonK Use technology to construct the confidence intervals for the population variance of and the population standard deviation o. Assume the sample is taken from a normally distributed population. c =0.90, s = 36, n = 18
