Hello. Can I get help on how to work this problem? Thank You!
Inspired by the example about how background music influences choice of entrée at a restaurant, a statistics student decided to investigate other ways to influence a person's behavior. Using 60 volunteers, she randomly assigned 20 volunteers to get a "red" survey, 20 volunteers to get a "blue" survey, and 20 volunteers to get a control survey. The first three questions on each survey were the same, but the fourth and fifth questions were different. For example, the fourth question on the "red" survey was "When you think of the color red, what do you think about?" On the blue survey, the question replaced red with blue. On the control survey, the last two questions were not about color. As a reward, each volunteer was allowed to choose a chocolate candy in a red wrapper or a chocolate candy in a blue wrapper. The table shows the result of the experiment. We want to test Ho: The distribution of candy choice is the same for subjects like these who receive the red survey, the blue survey,…
Even though Puerto Rico is a commonwealth of the United States, there are many cultural differences between the states on the continent and the island of Puerto Rico. These differences include the way consumers handle problems with purchases. Two researchers surveyed owners of DVD players in the Northeast United States and in Puerto Rico. They asked those who had experienced problems with their DVD players whether they complained. The results are given in the table below. Location Complained?

Rewrite the following sentence to remove its primary problem "We hypothesize that grade level has an effect on academic success."
Numerous studies have shown that watching too much television hurts children’s school grades. Others have argued that television is not necessarily a bad thing for children (Mail Online; July 2009). Like books and stories, television not only entertains, it also exposes a child to new information about the world. While watching too much TV is harmful, a little bit may actually help. Suppose a researcher gathers information on the grade point average (GPA) of 28 middle school children and the number of hours of TV they watch per week. GPA Hours TV 3.24 19 3.1 21 3.24 18 2.61 30 3.03 23 3.37 10 1.6 36 3.2 10 2.96 13 2.18 31 2.5 33 2.95 4 2.72 25 3.05 21 3.45 8 2.49 27 3.62 11 2.33 29 2.36 30 3.28 10 3.35 15 2.64 18 2.88 24 2.02 29 2.6 22 3.18 21 3.31 4 a.

Below you will find a research scenarios. Your task is to identify the proposed analysis and why you chose that analysis for each of these scenarios. State the research question that aligns with the scenario and the analysis. Next run the appropriate analyses and report your findings in APA Research scenario 2: Historians are interested in the accuracy of eyewitness accounts of traumatic events. One study examined survivors' recall of the sinking of the ship Titanic (Riniolo, Koledin, Drakulic, & Payne, 2003). The researchers reviewed the transcripts of survivors' testimony at governmental hearings (www.titanicinquiry.org) to see whether they testified that the ship was intact or breaking apart during the ship's final plunge (it was in fact breaking apart). To test for eyewitness accuracy, testimony of 20 survivors was examined to see if there was an equal likelihood of survivors saying the ship was intact or breaking apart. Datafile: titanic.xlsx Your response should contain…
