Suppose diastolic blood pressure for females in the United States is normally distributed with a mean Ī¼ = 75 mmHg and standard deviation Ļ = 12.7 mmHg. What proportion of women in this population have diastolic blood pressure between 68 and 93 mmHg?
Added by Sydney H.
Step 1
We can do this by subtracting the mean and dividing by the standard deviation: z1 = (68 - 75) / 12.7 = -0.55 z2 = (93 - 75) / 12.7 = 1.42 Show moreā¦

Among females in the United States between 18 and 74 years of age, diastolic blood pressure is normally distributed with mean Āµ = 77 mm Hg and standard deviation Ļ = 11.6 mm Hg. Find the upper and lower bounds of diastolic blood pressure between which 90% of the women find their diastolic blood pressure values.

The systolic blood pressure (in millimeters) of males has an approximately normal distribution with mean Ī¼ = 125 and standard deviation Ļ = 14. Find the 80th percentile of the distribution of systolic blood pressures. Round to the nearest whole number.

In Exercises 6ā10, assume that women have diastolic blood pressure measures that are normally distributed with a mean of 70.2 mm Hg and a standard deviation of 11.2 mm Hg (based on Data Set 1 āBody Dataā in Appendix B). Diastolic Blood Pressure Find the probability that a randomly selected woman has a diastolic blood pressure level between 60 mm Hg and 80 mm Hg.
