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 132.6 mmHg , with a standard deviation of 6.9 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 mmHgandmmHg. (Round your answer to 1 decimal place.) (b)According to Chebyshev's theorem, at least ▼(Choose one) of the measurements lie between 118.8 mmHg and 146.4 mmHg

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

132.6
mmHg
, with a standard deviation of
6.9
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
mmHgandmmHg.
(Round your answer to 1 decimal place.)
(b)According to Chebyshev's theorem, at least ▼(Choose one) of the measurements lie between
118.8
mmHg
and
146.4
mmHg
.
