Dr. Rodriguez was interested in how quickly students help someone who has fallen and who was perceived as having a health problem as compared to someone who has fallen but was not perceived as having a health problem. Dr. Rodriguez was also interested in whether the number of students who witness the fall affected how quickly students would help the person who fell. Dr. Rodriguez recruited 18 college students and offered to pay them $5 each for participating in a psychological study. She randomly assigned students to each group. She had two confederates participate in the study; one used a cane for the study, and the other did not. Dr. Rodriguez had either one, three, or five students wait in what they were told was a waiting room before the study began. The confederates were instructed to fall shortly after all of the participants entered the waiting room. There was a one-way mirror in the room, and Dr. Rodriguez recorded how long it took for the participants to respond to the person who fell. After the study, Dr. Rodriguez thanked the participants and dismissed them. The results of the study are represented in the tables below. Assume all differences are significant. Dr. Rodriguez concluded that both the number of students in the room and whether the person who fell was perceived as having a health problem affected how quickly students responded to the person who fell.

Answer 1

Answer:

Kindly check explanation

Explanation:

Given the data :

Person perceived as having health problem

No witnessing fall _____ secs it takesto respond

1 _______________25

3 ______________ 60

5 ______________ 180

Person perceived as not having health problem

No witnessing fall _____ secs it takesto respond

1 _______________90

3 ______________ 180

5 ______________ 360

A.)

The dependent variable, also the predicted variable is 'how quickly students respond to the person who fell'

The Independent variable refers to the predictor variable which influences the outcome of the dependent variable. The independent variables are ;

Number of students in the room ;

Perception of health problem in the person who fell.

2.)

The possible confounding variable may be the cane being held by one of the confederates, as this might cause a disruptive association between the dependent and independent variable.

3.)

From the result of the experiment, it could be observed that there is a positive trend between the number of witnesses(student in the room) and the time it took students to respond to someone who has fallen.

4.

Σfx / Σf

[(90*1) + (180*3) + (360*5)] ÷ (1+3+5)

= 270

a.

Descriptive statistics uses statistical measures to describes the numerical or quantitative measures of a data. Descriptive statistics sucha as mean, median, mode and so on.

Inferential statistics is used to make possible deductions or predictions from a data sample. It allows us to make conclusions about a certain population from a sample to f the population data.

b.

Based on Inferential statistics and hypothesis testing of the sample data, various hypothesis test statistics may be used to establish or conclude about a population characteristics from sample data.

Describe the pioneer travel experience to the frontier

Answers

Answer:

American pioneers were people who, in different periods of US history, but especially in the 18th century and the first half of the 19th century, moved westward, settling new territories.

Some of the pioneers migrated to establish farms with their families. Others were trappers or went west to engage in various types of business, with no intention of settling there forever.   Most of the pioneers went to the West in wagon caravans. These people cut down forests, built themselves log cabins, and drove the Indians out of the lands they occupied.  

The more settlers arrived in uninhabited places, the more among them became not hunters, but farmers. The most enterprising people bought plots of land on the cheap, and when it became more expensive, they sold it to the next settlers, and they themselves moved on, paving the way for others.

Pls help me

Answers

Answer:

Hatshepsut, daughter of King Thutmose I, became queen of Egypt when she married her half-brother, Thutmose II, around the age of 12. Upon his death, she began acting as regent for her stepson, the infant Thutmose III, but later took on the full powers of a pharaoh, becoming co-ruler of Egypt around 1473 B.C. As pharaoh, Hatshepsut extended Egyptian trade and oversaw ambitious building projects, most notably the Temple of Deir el-Bahri, located in western Thebes, where she would be buried. Depicted (at her own orders) as a male in many contemporary images and sculptures, Hatshepsut remained largely unknown to scholars until the 19th century. She is one of the few and most famous female pharaohs of Egypt.

I NEED HELP"Under the Constitution, voters in a presidential election are really electing groups of people called electors. These electors meet in what is known as the Electoral College. There they cast the ballots that actually elect the president and vice president. Each state has as many electoral votes as it has members of Congress.At that time, the Constitution said that electors were to cast two ballotswithout indicating which was for president and which was for vice president. The candidate with the majority of votes became president, and the candidate with the next-largest number of votes became vice president. In 1800, 73 electors cast their ballots for Jefferson and Burr. Each candidate, therefore, got the same number of votes. The Democratic-Republicans had won, but, because of the tie vote, the House of Representatives had to decide which candidate would become president.In the House, Federalists tried to keep Jefferson from becoming president by supporting Burr. For 35 ballots, the election remained tied. Finally, one Federalist decided not to vote for Burr.Because no one wanted to see another tie between a presidential and vice-presidential candidate, Congress passed the Twelfth Amendment to the Constitution in 1803.
