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 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 130.7 mmHg, with a standard deviation of 5.2
mmHg.
Assume that the article reported correct information. Complete the following statements about the distribution systolic blood pressure measurements for
women over seventy-five.
of the measurements
(a) According to Chebyshev's theorem, at least 7
lie between 120.3 mmHg and 141.1 mmHg.

?
(b) According to Chebyshev's theorem, at least 84% of the measurements lie
between ImmHg and ImmHg. (Round your answer to 1 decimal place.)
