Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters, for a sample of 6 adults. The following table presents the results. The least-squares regression line y =be+b,x=111.1246 -0.2740x, s.7.0225868, (-x) = 187.33, and x = 119.67 are known for this data. Diastolic Systolic...

Question 14 A medical researcher is studying the effects of a drug on blood pressure. Type numbers in the boxes. Subjects in the study have their blood pressure taken at the beginning of the 10 points 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...
