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...

Loretta, who turns 91this year, has heard that the mean systolic blood pressure among the elderly is 120 millimeters of mercury (mmHg), but she believes that the actual value is higher. She bases her belief on a recently reported study of 22 randomly selected, elderly adults. The sample mean systolic blood pressure of the adults in the study was 131mmHg, and the sample standard deviation was 22 mmHg. Assume that the population of systolic blood pressures of elderly adults is...

When 14 different second-year medical students measured by the systolic blood pressure of the same person, they obtained the results listed below (in mmHg). Assuming that the population standard deviation is known to be 15 mmHg, use a 0.05 significance level to test the claim that the mean blood pressure level is less than 140 mmHg. Hyper- tension is defined to be a blood pressure level that is too high because it is 140 mmHg or greater. Assume the blood...

- Blood Pressure For women aged 18–24, systolic blood pressures (in mm Hg) are nor- mally distributed with a mean of 114.8 and a standard deviation of 13.1 (based on data from the National Health Survey). Hypertension is commonly defined as a sys- tolic blood pressure above 140. a. If a woman between the ages of 18 and 24 is randomly selected, find the probabil- ity that her systolic blood pressure is greater than 140. b. If 4 women in...
