In the same blood pressure study described previously, the systolic blood pressure for men and women grouped together had a mean of 120.1 mmHg with a standard deviation of 15.1 mmHg. Using the empirical rule, what percentage of the population would you estimate to be between 105.0 and 165.4 mmHg? Give your answer as a percentage rounded to one decimal place and don't include units (don't write mmHg or a percent sign). Use a z-table such as https://www.math.arizona.edu/~rsims/ma464/standardnormaltable.pdf or an online calculator such as http://onlinestatbook.com/2/calculators/normal_dist.html to answer the following question: This question again refers to the study on blood pressure. What proportion of the population has a blood pressure that is below the value 113.7 mmHg for a normally-distributed set of blood pressures with a mean of 120.1 mmHg and a standard deviation of 15.1 mmHg? Express your answer as a percentage rounded off to 1 decimal place.
Suppose that diastolic blood pressure readings of adult males have a bell-shaped distribution with a mean of 8080 mmHg and a standard deviation of 1111 mmHg. Using the empirical rule, what percentage of adult males have diastolic blood pressure readings that are greater than 102102 mmHg? Please do not round your answer.
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 133.7 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 36% of the measurements lie between _? mmHg and _?mmHg. (Round your answer to 1 decimal place.) b. According to Chebyshev's theorem, at least _?% of the measurements lie between 119.9 mmHg and 147.5 mmHg.
