In 200 words explain.....Despite both theoretical and empirical evidence that a small amount of offenders commit the majority of crimes, three strikes legislation has failed at identifying and incarcerating this population. Based on your understanding of chronic offenders and the three strikes legislation, how would you alter this legislation to increase its effectiveness at reducing crime and targeting the chronic serious offender? Make sure to defend your position by incorporating course material.

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 131.5mmHg, with a standard deviation of 5.7mmHg.
Assume that the article reported correct information. Complete the following statements about the distribution of systolic blood pressure measurements for women over seventy-five.
