7) The following are the systolic blood pressures (mm Hg) of 12 patients undergoing drug therapy for hypertension: 183, 152, 178, 157, 194, 163, 144, 114, 178, 152, 118, 158. Assume normality, Can we conclude on the basist f these data that the population mean is less than 165 mm Hg? Use a-0.05.

The following is the systolic blood pressure (mm Hg) of 12 patients treated with hypertension drugs:
Systolic Blood Pressure (BP) is the pressure of blood circulating in the walls of blood vessels.
Most of this pressure is caused by the heart pumping blood through the circulatory system.
When used without degrees, the word "blood pressure" means pressure in the arteries.
Blood pressure is usually expressed in terms of the systolic pressure (high pressure during a single heartbeat) over diastolic pressure (low pressure between two heartbeats) in the heart cycle.
It is measured in millimeters of mercury (mmHg) above ambient air pressure.
Even if your diastolic number is normal (less than 80), you may have high blood pressure if your systolic count is 120-129.
If you have normal blood pressure, your blood pressure is below 120/80.
Stick to an active lifestyle and a healthy diet to keep that going.
The average error of a man is 158.
Use both p-values: Researchers reported the following systolic blood pressure (mm Hg) from randomized controlled trials to drug treatment for high blood pressure.
183, 152, 178, 157, 194, 163, 144, 114, 178, 152, 118, 158 a.
