Question

A doctor at a walk-in clinic is studying high blood pressure among patients aged twenty to forty. According to the American Heart Association, a person has high blood pressure if their Systolic and Diastolic readings are above 139 and 89 respectively. A random sample of 14 patients revealed the following blood pressures, where the readings (x,y) correspond to (Systolic, Diastolic) blood pressures. (190, 110) (129, 80) (119, 79) (190, 120) (160, 109) (179, 100) (129, 80) (120, 84) (179, 100) (180, 120) (129, 80) (140, 90) (139, 85) (119, 79) Assume that the population distribution is normal. For full marks, your answer should be accurate to at least two decimal places. a) Find the mean systolic reading of blood pressure for this sample. Mean = 0 b) Obtain a point estimate of the population mean of systolic blood pressures. Estimate of Population Mean = 0 c) Construct a 99-percent confidence systolic reading estimate for the population mean. Confidence Interval = (0, 0) d) Can we conclude that these patients have a mean systolic reading in the high blood pressure area? From our findings, we can conclude that the patients have a high mean blood pressure. From our findings, we cannot conclude that the patients have a high mean blood pressure.

Assume that the population distribution is normal. For full marks, your answer should be accurate to at least two decimal places.

a) Find the mean systolic reading of blood pressure for this sample.
Mean = 0

b) Obtain a point estimate of the population mean of systolic blood pressures.
Estimate of Population Mean = 0

c) Construct a 99-percent confidence systolic reading estimate for the population mean.
Confidence Interval = (0, 0)

d) Can we conclude that these patients have a mean systolic reading in the high blood pressure area?
From our findings, we can conclude that the patients have a high mean blood pressure.
From our findings, we cannot conclude that the patients have a high mean blood pressure.
