Four researchers, warren, xavier, yolanda, and zelda have devised different operational measures for gauging individual's levels of political knowledge. each researcher's operational measure is a scale ranging from 0 (low knowledge) to 100 (high knowledge). for the purposes of this exercise, assuming you know – but the researches do not – that the "true" level of knowledge of a test responding is equal to 50. the researchers measured the respondent four times here are the measurements obtained by each of the four researchers: warren: 40, 60, 70, 45 xavier: 48, 48, 50, 54 yolanda: 49, 50, 51, 50 zelda: 45, 44, 44, 46 which researcher's operational measure has low validity and low liability

i did the calculation and discovered that the empire state is 441.96 meters tall, and the page is 27.94 centimeters tall. a and b don't leave you with enough room on the page, c leaves too much, d is wrong because a page doesn't have 441.96 centimeters in it, and f would also leave too much space. to check that e is the correct answer, we can divide 441.96 by 50 to get 8.83. the scale model will be short, but it yields the best results comparative to the rest. i'm so sorry if this is wrong, it just doesn't seem that there's a better answer.

answer; /// i believe the correct answer is general act charters;

it would be d). more resources must be obtained to attain that combination of goods and services
