Aresearcher randomly selects and measures the volumes of the contents of 1212 bottles of cough syrup. assume the sample is taken from a normally distributed population. the 9090% confidence interval for the population standard deviation sigmaσ is (0.02490.0249,0.04420.0442). the population standard deviation of the volumes of the bottles' contents should be less than 0.0410.041 fluid ounce. does the confidence interval for sigmaσ suggest that the variation in the volumes of the bottles' contents is at an acceptable level? explain your reasoning.
