Please find attached the figure with the complete question including the histogram
Answer:

Explanation:
You must understand the <em>histogram.</em>
The horizontal axis shows the <em>weights in pounds</em> measured using the central points of the intervals. The intervals are supposed to be [105,115], [115,125], [125,130], . . .
The height of the bars represents the frequencies or number of <em>members </em>for each interval. You can read the height of each bar on the vertical axis.
Thus, you find the number of members for each interval:
- first interval: 5 members
- second interval: 4 members
- third interval: 2 members
- fourth interval (blank): 0 members
- fifth interval: 5 members
- sixth interval (blank): 0 members
- seventh interval: 4 members
Total: 5 + 4 + 2 + 0 + 5 + 0 + 4 = 20 members ← answer
Answer:
Social exchange theory
Explanation:
Social exchange theory is the theory that says that social behavior is the result of an exchange process.
According to this theory, people weigh the potential benefits and risks of their actions. When the risks outweigh the rewards, people will not engage in the action or conduct.
In this case, <u>Person A donated money because the potential benefits included the boost of her self-esteem</u>, since this weight too much to this person, she donated the money.
On the other side, <u>the risks for Person B outweighed the rewards, since he was fearful or running out of money </u>and therefore he did not donate it.
Maybe because they need to understand it in order to teach us how to do so that’s why they have to go to college and get their degree also to understand social stratification
