A drug which is used for treating acne 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 19 dosages of tablet "A" is 0.013. The sample variance of a sample of 66 dosages of tablet "B" is 0.006. Construct the 95%confidence interval for the ratio of the population variances. Round your answers to five decimal places.

A drug, which is used for treating cancer, has potentially
dangerous side effects if it is taken in doses which are larger
than 41.54mg , the required dosage for the treatment. It is
important that the variance of the amount of the active ingredient
is 0.04. 12 tablets are randomly selected and the amount of the
drug in each tablet is measured. It is determined that the variance
of the amount of active ingredient is 0.0291mg . Does the data...

A drug which is used for treating cancer has potentially
dangerous side effects if it is taken at an improper dosage. The
drug is manufactured at two different plants, plant A and plant B.
A medical researcher believes that tablet A has a smaller variance
in dosage than the variance in dosage from tablet B. The sample
variance of a sample of 13 dosages of tablet A is 0.01. The sample
variance of a sample of 18 dosages of tablet...

A drug which is used for treating high blood pressure has
potentially dangerous side effects if it is taken at an improper
dosage. The drug is manufactured at two different plants, plant A
and plant B. A medical researcher believes that tablet A has a
smaller variance in dosage than the variance in dosage from tablet
B. The sample variance of a sample of 6 dosages of tablet A is
0.009. The sample variance of a sample of 20 dosages...

Two competing drugs are available for treating a specific
ailment. There are no apparent side effects from drug 1. Whereas
(nausea and headaches from drug 2. A group of researchers has
decided however that they are willing to recommend drug 2 if the
proportion of cures for drug 2 is higher than that of drug 1. The
researchers use both drugs experimentally on people who are
suffering from the ailment. By the end of experiment 52 of 80

A researcher is interested in the effects of a psychedelic drug
in treating post-traumatic stress disorder (PTSD). To assess if the
psychedelic may be effective in attenuating the severity of PTSD
symptoms, she performs a pilot experiment to compare the effects of
the psychedelic to the commonly‑prescribed selective serotonin
reuptake inhibitor (SSRI) Sertraline in individuals diagnosed with
PTSD. The amount of the psychedelic was selected based on an online
forum in which recreational drug users describe their drug-taking
