Systolic blood pressure has a mean of 80 and a standard deviation of 8. a. What is the probability a person will have a reading between 75 and 85? What is the probability that the average reading of 9 people will be between those values? What reading would put you in the highest 10% of readings?

Loretta, who turns eighty this year, has just learned about blood pressure problems in the elderly and is interested in how her blood pressure compares to those of her peers. Specifically, she is interested in her systolic blood pressure, which can be problematic among the elderly. She has uncovered an article in a scientific journal that reports that the mean systolic blood pressure measurement for women over seventy-five is 133.8 mmHg, with a standard deviation of 6.3 mmHg. Assume that...

6. A sample of 800 adults had a bell-shaped symmetric blood pressure with the mean of 125 and standard deviation of 10. a. Use the empirical rule to find the 68% range b. Use the empirical rule to find the usual range c. Complete the following bell shaped distribution and answer the following: i. What percent of data fall within 115 to 145? ii. How many of those adults have blood pressure within 115 to 145?

A health study reported that, in one country, systolic blood pressure readings have a mean of 119 and a standard deviation of 15 . A reading above 140 is considered to be high blood pressure. Complete parts a through d below. a) What is thez-score for a blood pressure reading of130? b) If systolic blood pressure in that country has a normal distribution, what proportion of the population suffers from high blood pressure? c) What proportion of the population has...

8. Normal blood pressure typically is defined as having systolic pressure < 120 and diastolic pressure <80. Among US residents age 40+, mean systolic pressure is 130 with a standard deviation of 35, and mean diastolic pressure is 80 with a standard deviation of 20. a) What is the probability that a US resident 40+ has high systolic blood pressure? b) What is the probability that a US resident 40+ does not have high diastolic blood pressure?

12. The systolic blood pressures of a sample of adults are normally distributed, with a mean pressure of 115 millimeters of mercury and a standard deviation of 3.6 millimeters of mercury. The systolic blood pressures of four adults selected at random are 121 millimeters of mercury. 113 millimeters of mercury, 107 millimeters of mercury, and 128 millimeters of mercury. The graph of the standard normal distribution is shown to the right. Complete parts (a) through (c) below. (a) Without converting...
