Question

In a recent study, the Centers for Disease Control reported that diastolic blood pressures of adult women in the U.S. are approximately normally distributed with mean 80.4 and standard deviation 9.9.

1. What proportion of women have blood pressures lower than 70? (Round the final answer to four decimal places.)

2. What is the 80th percentile of blood pressures? (Round the final answer to two decimal places.)

3. A woman has a blood pressure of 84 mm. What percentile is her blood pressure on?

4. A diastolic blood pressure greater than 90 is classified as hypertension (high blood pressure). What proportion of women have hypertension? (Round the final answer to four decimal places.)

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
