A drug which is used for treating low blood pressure has potentially dangerous side effects if it is taken in doses which are larger than the required dosage for the treatment. A medical researcher believes that the variance in dosage is different for two tablets made by different production facilities. The sample variance of a sample of 11 dosages of tablet "A" is 0.005. The sample variance of a sample of 29 dosages of tablet "B" is 0.002. Construct the 95 % confidence interval for the ratio of the population variances. Round your answers to four decimal places.
