From each drop-down menu, select the option that creates the most accurate statement based on the information presented in the graph.
1.1 The correlation between the systolic and diastolic pressure readings is weakest for Patient ____________.Kindly refer the image for details:
Patient-AWe can see that there is a clear positive correlation between the systolic and diastolic pressure. With an increase in systolic pressure there is an increase in diastolic pressure.
Patient-BNo proper inference can be drawn about the correlation. Even when the the systolic pressure is increasing the diastolic pressure is decreasing on Day 4 & Day 7, and vice versa is the case on Day 3 & Day 6.
Patient-CWe can see that there is a positive correlation between the systolic and diastolic pressure. When the systolic pressure is increasing the diastolic pressure is either increasing or constant, but in no case the diastolic pressure is decreasing.
So, Option B.
A. A
B. BC. C
1.2 The standard deviation of systolic blood pressure readings among the patients was lowest on Day __________.The standard deviation will be minimum when the pressure readings are closer to one another. We can find the range and and arrive at the conclusion.
On this basis the range of systolic pressure on:
Day-1 - 70
Day-2 - 40
Day-3 - 30
Day-4 - 19
Day-5 - 29
Day-6 - 22
Day-7 - 11
A. 3
B. 5
C. 6
D. 7So, the correct answers are B & D
