Caleb designed an experiment to investigate whether listening to music or chewing gum affects the time to completea level of a certain video game. Before the game started, each person in a sample was randomly assigned to eitherlisten to music or not listen to music. Each person was also randomly assigned to either chew gum or not chew gum.At the end of the game, the time to complete the level for each person in the sample was recorded.Which of the following correctly identifies the response variable of the experiment and whether the variable iscategorical or quantitative?(A) The response variable is the time to complete the level and the variable is quantitative.(B) The response variable is the time to complete the level and the variable is categorical.(C)The response variable is whether the person was assigned to listen to music or chew gum and the variable iscategorical.The response variable is whether listening to music or chewing gum affects time to complete the level and(D) the variable is quantitative.(E)The response variable is whether listening to music or chewing gum affects time to complete the level andthe variable is categorical.

The objective of the question is to identify the response variable in the experiment and determine…

The scenario A professor wanted to learn more about the students at her university with regards to whether they prefer in-person or online classes. She randomly sent out surveys to students at the university . Of the students that responded, % prefer taking online classes. The questions Use the information from the scenario to answer the following: What is the population that this study is trying to get information about? What is the variable used for the study? What type of variable is the variable in question 2? What is the sample statistic for this study? What is the parameter of interest for this study? (the population parameter they are trying to gather information about)
In a statistics activity, students are asked to spin a penny and a dime and determine the proportion of times that each lands with tails up. The students believe that since a dime is lighter, it will have a lower proportion of times landing tails up compared to the penny. The students are instructed to spin the penny and the dime 30 times and record the number of times each lands tails up. For one student, the penny lands tails side up 18 times, and the dime lands tails side up 20 times. Let PD = the true proportion of times a dime will land tails up and pp = the true proportion of times a penny will land tails up. Which of the following is the correct standardized test statistic and P-value for the hypotheses, Ho: Po-Pp= 0 and H₂: Po-Pp<0?
A randomly sampled group of patients at a major U.S. regional hospital became part of a nutrition study on dietary habits. Part of the study consisted of a 50-question survey asking about types of foods consumed. Each question was scored on a scale from one (most unhealthy behavior) to five (most healthy behavior). The answers were summed and averaged. The population of interest is the patients at the regional hospital. The current survey was implemented after patients were subjected to this education, and it produced the following sample statistics for 25 patients sampled: and s = 1.02. We would like to know if the education improved nutrition behavior. We test the hypotheses H 0: = 2.9 versus Ha: > 2.9. The value of the t test is 1.96, and: a. P-value > 0.1. b. 0.025 P-value < 0.05. c. 0.25 P-value < 0.01. d. 0.05 P-value < 0.1. Given the least squares regression line y = 3 x – 3, which of the following is true? a. The…
A city official would like to know if there is public support for increasing funding for arts programs. To collect data, the city official stands outside a concert hall after a show and surveys every 25th person to exit and asks their opinion about raising funds for the arts. Which of the following describes the population in this scenario? all residents of the city the members of the city council all city residents who support the arts the people surveyed by the city official
Sean is the star shortstop for his baseball team. He notices that his team typically scores about half as many runs as he has singles, and that his team is about 10% more likely to win a game for each run scored. How likely is it that the team wins if he has 6 singles? How many singles did Sean hit if the team was 70% likely to win?
A consumer group wanted to determine if there was a difference in customer perceptions about prices for a specific type of toy depending on where the toy was purchased. In the local area there are three main retailers: W-Mart, Tag, and URToy. For each retailer, the consumer group randomly selected 5 customers, and asked them to rate how expensive they thought the toy was on a 1-to-10 scale (1= not expensive, to 10 = very expensive). The toy was priced the same at all retail stores. Compute the percentage of variance explained by the group differences for these data. Q: Percentage and variance explained = ?
A fundraiser is offering a small gift to people making a donation. The donor can choose one of four gifts: a mug, a t-shirt, a plush toy, or a water bottle. The fundraiser would like to know if any of the gifts were more or less popular or were they equal in preference. The data for n = 40 donors are below:

Let pp = the true proportion of times a dime will land tails up and pp = the true proportion of times a penny will land tails up. The P-value for this significance test is 0.296. Which of the following is the correct conclusion for this test of the hypotheses H Pp-Pp=0 and H, Po-Pp 0.05. There is sufficient evidence that the true proportion of times a dime will land tails up is significantly less than the penny. O The student should reject the null hypothesis since 0.296 > 0.05. There is insufficient…
15 wheelchair users were randomly assigned to three groups with 5 in each group. These participants navigated in virtual-reality settings. Group 1 participants were in the virtual-reality setting (a building) as wheelchair users. Group 2 participants were in the virtual-reality setting in a wheelchair pushed by a walking person. Group 3 participants walked without aid in the virtual-reality setting. Joan measured the time each participant needed to complete the navigation of the virtual-reality setting. What is the independent variable(s)?
