For women aged 18-24, systolic blood pressures ( in mm Hg) are normally 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 systolic blood pressure above 140. If 4 women in that age bracket are randomly selected, what is the probability that their mean systolic blood pressure is above 140?

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...

1. The National Center for Health Statistics reports that the systolic blood pressure for males 35 to 44 years of age has a mean of 128. In a study of business executives, a random sample of 101 executives has a mean systolic blood pressure of 134 with a standard deviation of 25. Do the data suggest that the mean systolic blood pressure for business executives is higher than 128? Use a 5% significance level?

The National Center for Health Statistics reports that the mean systolic blood pressure for males 35 to 44 years of age is 128 mmHg and the standard deviation in this population is 15 mmHg. The medical director of a large company looks at the medical records of 72 executives in this age group and finds that the mean systolic blood pressure in this sample is x 126.07 mmHg. Find the power of a one sided test that the executives blood...

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...

Assume that systolic blood pressure readings are normally distributed with mean 120 and standard deviation of 5.8. A researcher wishes to select people for a study but wants to exclude the top and bottom 12 percent. What would be the upper and lower readings to qualify people to participate in the study?
