Check our blood pressure: In a recent study, the Centers for Disease Control and prevention reported that diastolic blood pressures of adult women in the United States are approximately normally distributed with mean 80.8 and a standard deviation of 10.2.

(a) What proportion of women have blood pressures lower than 69?

(b) What proportion of women have blood pressures between 70 and 90?

(c) A diastolic blood pressure greater than 90 is classified as hypertension (high blood pressure). What proportion of women have hypertension? (

d) Is it unusual for a woman to have a blood pressure lower than 62? Round the answers to four decimal places.

The United States Centers for Disease Control and Prevention (CDC) found that 17.9% of women ages 12 – 59 test seropositive for HPV‑16. Suppose that Tara, an infectious disease specialist, assays blood serum from a random sample of ?=1000 women in the United States aged 12 – 59. Apply the central limit theorem for the distribution of a sample proportion to find the probability that the proportion, ?̂ , of women in Tara's sample who test positive for HPV‑16 is...

Hypertension is when an adult is classified as having high blood pressure (above 130 systolic blood pressure is considered hypertension). Researchers want to know the proportion of adult North Americans (above age of 18) that have hypertension. Based on a study of 3532 adult North Americans, 1219 of them were classified as having hypertension. a)Researchers want to test if more than a quarter of all North American adults have hypertension (that is to say more than 25% proportion of North...
