Caterpillar has been researching the idea of replacing the traditional steering mechanism on its graders with a joystick based s

Operators were then randomly assigned to use one of the two types of graders for a few days. After three days of testing, the joystick operators were much more satisfied than the steering wheel operators. This would be an example of using _______ research.

What is the breakdown of ethincity of the voting members of the 113th congress?
fgiga [73]
Almost one-in-five members of the House and Senate are a racial or ethnic minority, making the 114th Congress the most diverse in history. However, Congress remains disproportionately white when compared with the U.S. population, which has grown increasingly diverse in recent decades, according to a Pew Research Center analysis.Overall, non-whites (including blacks, Hispanics, Asian/Pacific Islanders and Native Americans) make up 17% of the new Congress, but that is below these groups’ 38% share of the nation’s population. This difference also exists among the newly elected members of Congress, as minorities account for 11 of 71 (15%) new members of the House and Senate. (No new senators are a racial or ethnic minority.)Diversity among congressional members has been growing for decades. But the nation’s population has diversified more quickly. When the 107th Congress took office in 2001, minorities accounted for 12% of Congress, compared with about 31% of the nation’s population. By comparison, in 1981, 6% of Congress was minority (black, Hispanic, Asian/Pacific Islander or Native American), while in the national population about 20% were non-white.

Stacy is participating in a local psychology experiment in which the research assistant asks stacy to hold two pencils in front
Katena32 [7]
<span>This demonstrates the importance of binocular cues. This demonstrates binocular cues because putting two pencils together with both eyes open is not too difficult but once you only use one eye, the task becomes much more difficult. Thus, binocular cues are important because they make many tasks, including this one, much easier.</span>
