After a three-month siege, Spanish forces under Hernán Cortés capture Tenochtitlán, the capital of the Aztec empire. Cortés' men leveled the city and captured Cuauhtémoc, the Aztec emperor.
Answer:
candy and no-candy condition
Marnie's strategy used researchers to find out the number of misbehaviors among the children( little enough to fit in shopping cart). She tries to pick chilren randomly by picking out every fifth child who is little enough to fit in cart for her research. She limits her research to certain age group.
Age group is the extraneous variable in the experiment
Ethical challenge: The researchers followed the child. So they had to be careful
mode in candy condition: 3
range in no candy condtion is 3
They can reduce number of mis-behaviors by disciplining them.
Explanation:
Independent variable: Candy and no-candy condition.
Her strategy is to pick chilren randomly so she directs researchers to pick every fifth child. She also restricts her research to a certain age group. The age group is restricted by making sure that child is small enough to fit in shopping cart.
age group. She controlled this by making sure children were small enough to fit in shopping cart.
The researchers followed the child around the store which is unethical. They must have been careful not to get noticed.
range in no-candy condition: 4-1=3
authoritative parenting help to discipline the children
According to the data, in those with roundabouts fewer accidents occur.
<h3>Why are Roundabouts safe?</h3>
- Roundabouts are a safer option than stop signs and traffic lights.
- Drivers must slow down to navigate a roundabout's narrow path, making head-on, right-angle, and left-turn collisions—the three most serious kinds of intersection crashes—unlikely.
- Roundabouts are more environmentally friendly and provide improved traffic flow.
- According to research, converting conventional crossroads to roundabouts enhances traffic throughput. Reduced idling lowers fuel use and emissions from vehicles.
- In general, roundabouts are safer for pedestrians. Around the perimeter, pedestrians use the sidewalks and only cross one lane of traffic at a time.
- Shorter crossing distances and slower traffic speeds than at conventional intersections are the norms.
Hence, in those with roundabouts fewer accidents occur.

Answer:
Control group; experimental group
Explanation:
Control group: In research, the term "control group" is described as a group through which specific comparisons are being made in research or experiment. The main purpose of the control group in an experiment whereby the effect of treatment is considered unknown and hence, the comparison between the experimental group and the control group are being utilized to measure the "effect of the treatment".
Experimental group: In research, the term "experimental group" determines the group of specific participants who are being exposed to an independent variable. Therefore, these participants are either exposed or receive the "treatment variable".
In the question above, the given statement represents the participants seeing "neutral faces" are in the control group and the participants seeing "smiling faces" are in the experimental group.
