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 of tablet B is
0.017. Test the claim using a 0.025 level of significance. Let σ12
represent the population variance for tablet A.
Q1: Compute the value of the test statistic. Round your answer to
four decimal places.
Q2: Find the P-value
Q3: Make a decision (Reject the null hypothesis or Fail to
reject the null hypothesis. Is there enough evidence to support the
null hypothesis, or not?).
GIVEN ANSWERS:
H0: σ21 ≥ σ22
Ha: σ21 < σ22

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 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...

A medical researcher is studying the effects of a drug on blood
pressure. Subjects in the study have their blood pressure taken at
the beginning of the study. After being on the medication for 4
weeks, their blood pressure is taken again. The change in blood
pressure is recorded and used in doing the hypothesis test. Change:
Final Blood Pressure - Initial Blood Pressure The researcher wants
to know if there is evidence that the drug reduces blood pressure.
