According to research done on the topic of trailer hitches and receivers, the best answer to your question: Which of the following hitches are not allowed, would be: Bumper hitch.
Explanation:
Hitches come in 5 major classifications, according to the research done online, and there are three major receiver classes, class I, II and III. The category of them, and which one is the best to be selected when going to hitch a trailer and cargo, would depend on their gross trailer weight, tongue weight and hitch receiver size, as well as the type of cargo and most particularly, the vehicle that will be pulling the trailer.
Answer:
Part A:
The cofounding variable is a factor that could cause a result on the experiment. This would be the people taking extra food.
Independent variable would be being asked to sign in or not and take free food, because independent variable is a variable that is changed or manipulated and in this case the people were split in half and the hypothesis is that the people who didn't sign in would take more food.
Operational definitions are important when conducting research because it defines all the variables in the experiment, so it can be replicated. The operational def for the dependent variable would be "Doing the right thing even though you aren't being watched"
Part B:
The data does not support the hypothesis because even the people who signed in could've taken extra food when the dean wasn't looking. The findings cannot be generalized to all students because some students could have been taught better and can differentiate between right and wrong. So the people who were not signed in could've just taken one burger and drink, and the people who were signed in might feel obligated to take more than one burger because they had signed in and didn't just come without signing in.
The study is not a naturalistic observation because the observer did not look at the people who took the food and which side took more food.
The correct answer is - GDP by what is supplied.
The best way to measure a GDP is by what is supplied on the market. Basically this means that the GDP should be measured by what and how much the economy is producing. The produced goods and services may be only for the country's market, or also for export, but those are the ones that bring in the money in the economy.
If the GDP was measured by what is demanded than we will have a very unrealistic picture. The reason is that the demand for numerous things can be there on the market, bu the financial power of the people may not actually correspond with it, nor the strength of the economy. A perfect example for something like this is Greece.
