A World Health Organization study (the MONICA project) of health in various countries reported that in Canada, systolic blood pressure readings have a mean of 123 and a standard deviation of 12. A reading above 149 is considered to be high blood pressure.
(a) How many standard deviations away from the mean is a blood pressure reading of 149? z = (3 decimal places)
(b) If systolic blood pressure in Canada is approximately normal, find the proportion of Canadians that suffer from high blood pressure. (3 decimal places)
(c) If systolic blood pressure in Canada is approximately normal, what is the probability that a randomly selected Canadian has a systolic blood pressures in the range from 102 to 149. (3 decimal places)

Question 5 [10 points] A doctor at a walk-in clinic is studying high blood pressure among patients of the ages twenty to forty. According to the American Heart Association, a person has high blood pressure if their Systolic and Diastolic readings are above 130 and 39 respectively. A random sample of 10 patients revealed the following blood pressures, where the readings (x,y) correspond to (Systolic Diastolic blood pressures (179,109) (180,120) (11970) (130,85) (159,90) (110,79) (180,120) (119,70) (110,79) (159,90) Assume that...
