A researcher randomly selects and measures the volumes of the contents of 11 bottles of cough syrup. Assume the sample is taken from a normally distributed population. The 95% confidence interval for the population standard deviation à is (0.0241,0.0444). The population standard deviation of the volumes of the bottles' contents should be less than 0.021 fluid ounce. Does the confidence interval for suggest that the variation in the volumes of the bottles' contents is at an acceptable level? Explain your reasoning. Choose the correct answer below. O A. No, because all values contained in the confidence interval are less than 0.021. OB. No, because all values contained in the confidence interval are greater than 0.021. OC. Yes, because 0.021 is contained in the confidence interval. O D. Yes, because all values contained in the confidence interval are greater than 0.021. O E. No, because 0.021 is contained in the confidence interval.
