Question

Laura, who turns eighty years old 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. She has uncovered an article in a scientific journal that reports that the mean systolic blood pressure measurement for women over seventy-five is 132.0 mmHg, with a standard deviation of 6.4 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 56% of the measurements lie between mmHg and mmHg. (Round your answer to 1 decimal place.) (b) According to Chebyshev's theorem, at least (Choose one) of the measurements lie between 119.2 mmHg and 144.8 mmHg.
