A group of medical researchers is conducting tests on patients to determine the effectiveness of a new medicine against hypertension. Patients with high blood pressure were randomly selected and assigned, also randomly, to a control group (received a known anti-hypertensive drug) or treatment group (received the new drug). Doctors recorded the percentage of patients whose blood pressure dropped to a normal level after one year of treatment. At the 0.01 level of significance, test the appropriate hypotheses to determine whether the new medicine is significantly more effective in lowering blood pressure than the known medicine. The alternative hypothesis is:

H 1 colon mu subscript 1 not equal mu subscript 2

H 1 equal P subscript 1 not equal P subscript 2

H 1 colon P subscript 1 equals P subscript 2

H 1 colon P subscript 2 less than end subscript P subscript 1
