Question

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 133.1 mmHg, with a standard deviation of 6.5 mmHg. Assume that the article reported correct information. Complete the following statements about the distribution of systolic blood pressure measurements for women over seventy-five. (a) According to Chebyshev's theorem, at least (Choose one) of the measurements lie between 120.1 mmHg and 146.1 mmHg. (b) According to Chebyshev's theorem, at least 84% of the measurements lie between mmHg and mmHg. (Round your answer to 1 decimal place.)

Step 1

Step 1: The Chebyshev inequality states that for any random variable X with mean μ and standard deviation σ, the probability that X takes on a value within k standard deviations of the mean is at least 1 - 1/k^2, where k is a positive real number greater than 1. Show more…
