Suppose the diastolic blood pressure of females follow Normal distribution with Mean = 80 and Standard deviation - 3. The probability that the diastolic blood pressure of a female is greater than 78 is given as None 0.5138 0.7475 0.2392 0
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 a mean of 80.5 and standard deviation 9.9. Round all answers to 4 decimal places. a. What proportion of women have blood pressures lower than 70? b. Find the 30th percentile for blood pressures. C. Suppose a sample of 150 women is taken. What is the probability that the sample mean blood pressure would be...

Suppose that diastolic blood pressure readings of adult males have a bell-shaped distribution with a mean of 84 mmHg and a standard deviation of 9 mmHg Using the empirical rule. what percentage of adult males have diastolic blood pressure readings that are greater than 102 mmHg? Suppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.62 and a standard deviation of 0.39 Using the empirical rule, what percentage of the students...
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?
QUESTION 16 Using the information below, answer the next two questions: A study measures blood pressure among college students. The lowest actual blood pressure is 70, and the highest is 130. Each blood pressure test is equally likely. It follows a uniform distribution. [Sean Hint: The data distribution has mean 100 and standard deviation 17.32). A sample of 100 students' blood pressure is taken. (a) What is the probability that the mean of blood pressure is less than 97. [HintFirst...

The mean diastolic blood pressure for a random sample of 60 people was 81 millimeters of mercury. If the standard deviation of individual blood pressure readings is known to be 12 millimeters of mercury, find a 90% confidence interval for the true mean diastolic blood pressure of all people. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. What is the lower limit of the 90% confidence...
A study measures blood pressure among college students. The lowest actual blood pressure is 70, and the highest is 130. Each blood pressure test is equally likely. A sample of 100 students’ blood pressure is taken. The mean is 100 and the standard deviation is 17.321. (a) What is the probability that the mean of blood pressure is less than 97.(Round to 4 decimal places) b) Find the 90 percentile for the mean of 100 blood pressure. (Round to 2 decimal...
The mean diastolic blood pressure for a random sample of 70 people was 90 millimeters of mercury. If the standard deviation of individual blood pressure readings is known to be 10 millimeters of mercury, find a 95% confidence interval for the true mean diastolic blood pressure of all people. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.) What is the...
