Answer:
The answer is D. Correlational design.
Explanation:
Correlational designs seek to study the relationship between two or more variables in a piece of research. For example, a news article called "Students with healthy diets get better grades at school" is probably based in a correlational study.
It's important to recognise that correlation is <u>not</u> the same as causation. This means: even if two variables appear to be related, that does <u>not</u> indicate a direct cause-effect relationship.
Southern states were known as the cotton kingdom because the cotton population in the south was rapidly growing. Rich plantation owners would grow cotton and sell them to the New England region to make clothes etc.

Answer:
Conditional probability of a student, who has actually plagiarized, answering "yes" to the survey is 0.375.
Explanation:
This is easily explanined if we first take the probability of each answer (yes / no) depending on what they fet flipping the coin.
- Tails [always yes] = 0.5 -> Plagiarism = 0.5
- Heads [yes or no] = 0.5 > Two option: (1) True Plagiarism = 0.3; (2) False Pagiarism = 0.7
Now, what we have to do is multiply the "yes" answers from both possible coin tosses (0.5 x 0.3) and divide them by the rest of probable answers (0.5, 0.5, 0.5 & 0.3).
Better expressed like this:
0. 5 x 0.3 / 0.3x0.5+0.5x0.5 = 0.375
The correct answer is B. It imports more goods than it exports.
Explanation
The trade deficit is the name by which the negative difference between what a country exports and what that same country imports from other countries is known. This serves as an indicator to analyze the internal and external trade relations of a country. When a country is in a trade deficit, it is when it has imported more goods and services than it has sold abroad. Therefore, if the United States imports more goods and services than it exports, it will be in a trade deficit. So the correct answer is B. It imports more goods than it exports.
