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 133.5 mmHg, with a standard deviation of 6.1 mmHg. Assume that...

Suppose that diastolic blood pressure readings of adult males
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...

Suppose that the distribution of snake lengths in a certain park is not assumed to be symmetric. According to Chebyshev's Theorem, at least what percentage of snake lengths are within k=2.9 standard deviations of the mean? Round your answer to the nearest whole number (percent).

Problem 3. According to a recent study the mean blood pressure for people in China is 128 mmHg with a standard deviation of 23 mmHg. Assume that blood pressure is normally distributed. (b)Find the probability that a person in China has blood pressure of140 mmHg or more. (c)Find the probability that a person in China has blood pressure of 135 mmHg or less. Continuing with this problem, suppose now a sample of 15 people are chosen from the above normal distribution...

Blood pressure (BP) in childhood tends to increase with age, but differently for boys and girls. Suppose that for boys and girls, mean systolic blood pressure is 95 mmHg at 3 years of age and increases 1.5 mmHg per year up to the age of 13. Furthermore, starting at age 13, the mean increases by 2 mmHg per year for boys and 1 mmHg per year for girls up to the age of 18. Finally, assume that blood pressure is...

(1 point) A statistician uses Chebyshev's Theorem to estimate that at least 95 % of a population lies between the values 7 and 18, Use this information to find the values of the population mean, μ , and the population standard deviation σ.

Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with a mean of μ=188 days and a standard deviation of σ=13 days. What is the probability that a randomly selected pregnancy lasts less than 184 days?

Loretta, who turns 91this year, has heard that the mean systolic blood pressure among the elderly is 120 millimeters of mercury (mmHg), but she believes that the actual value is higher. She bases her belief on a recently reported study of 22 randomly selected, elderly adults. The sample mean systolic blood pressure of the adults in the study was 131mmHg, and the sample standard deviation was 22 mmHg. Assume that the population of systolic blood pressures of elderly adults is...

According to a recent study, the carapace length for adult males of a certain species of tarantula are normally distributed with a mean of μ=17.24mm and a standard deviation of σ=1.68 mm. Find the percentage of the tarantulas that have a carapace length between 15 mm and 16 mm.
