- A recent study of 1000 high school juniors and seniors asked whether or not they felt smartphones are a valuable learning tool. Additional data were gathered on their smartphone plan (unlimited data, additional texting, or standard voice plan) and which class they were in (junior vs. senior). Which of the following is a correct pair of hypotheses the researchers could test? (A) Ho: The proportion of juniors and seniors who feel smartphones are a valuable learning tool is the same for students that have each type of plan. Ha: The proportion of juniors and seniors who feel smartphones are a valuable learning tool is not the same for students that have each type of plan (B) Ho: The proportion of students who feel smartphones are a valuable learning tool is the same for students that have each type of plan. Ha: The proportion of students who feel smartphones are a valuable learning tool is not the same for students that have each type of plan. (C) Ho: There is an association between class…Investigation 3.2: Valence Differences Between R&B and Rap Genres (Paired)A music fan claims that R&B songs tend to have a more positive tone on average than do Rapsongs. The individual collected two independent random samples from the population of SpotifySongs. Fifteen R&B songs and another fifteen Rap songs were collected and their Valence wasrecorded. The music fan believed that pairing the song by their Danceability may provideadditional information. Danceability describes how suitable a track is for dancing based on acombination of musical elements including tempo, rhythm stability, beat strength, and overallregularity. A value of 0.0 is least danceable and 1 is most danceable. Thus, the individual pairedthe R&B song with the lowest danceability with the Rap song with the lowest danceability,followed by the second and second, third and third. She continued this process until the R&Bsong with the highest danceability was paired with the Rap song with the…Annie conducts a study to examine the differences in stress levels between pet owners and non-pet owners. She conducts a two-tailed test and tells that she rejected the null hypothesis. Therefore, which of these statements is true? Question 8 options: Pet owners have more stress than non-pet owners. Pet owners have less stress than non-pet owners. Pet owners' and non-pet owners' stress levels differ, but it is not known how they differ. Pet owners' and non-pet owners' stress levels do not differ.
- Management of a theater in a large city wants to know whether its popularity increased after it ran a popular musical. According to a previous study, 25% of city residents said they had been to the theater in the past year. A more recent study, conducted after the musical had run for a year, found that 156 of 536 residents sampled said they had been to the theater in the past year. Is there evidence at the ? = 0.05 level that the number of residents who have been to the theater has increased in the last year?Chapter 9. 6)A poll surveyed 341 video gamers, and 81 of them said that they prefer playing games on a console, rather than a computer or hand-held device. An executive at a game console manufacturing company claims that the proportion of gamers who prefer consoles differs from 26 %. Does the poll provide convincing evidence that the claim is true? Use the 0.05 level of significance and the P-value method. 7S K The concerns about the impact of technology on our lives are growing. There have been recent research reports about the negative impact of digital technology usage on stress, work productivity, happiness, and overall well-being. In light of these concems, a polling organization asked technology experts about their opinion on our digital life and found that 28% of the experts believe that in the future our lives will be more harmed than helped by their digital environment. In an effort to confirm these results, a local tech company decides to ask 210 randomly selected customers their opinions about their digital life. Answer parts a through c below. a. What is the probability that 35 or more people from this sample are concerned about the digital environment? The probability is 1. (Round to four decimal places as needed.) b. What is the probability that 45 or more people from this sample are concerned about the digital environment? 0. (Round to four decimal places as needed.) The…
- In a UK business school, lecturers have tried to determine if the number of hours students attend lectures has any measurable effect on the grades obtained by the students. The following data from a sample of 14 students in an international business class show hours of attendance and resulting grades.(22, 72), (20, 64), (24, 70), (8, 34), (12, 40), (16, 40),(18, 52), (16, 45), (20, 68), (24, 65), (28, 72),(20, 64), (10, 38), (16, 44)a. Estimate the regression line.b. Find a 95% confidence interval for the slope of the regression line.Roediger and Karpicke (2006) investigated whether the test-enhanced learning effect (the demonstration that repeated testing improves memory for material) was due merely to repeated exposure to material. They randomly assigned participants to one of two conditions(study-study or study-test) and to one of three interval conditions (final test at a delay of 5 minutes, 2 days, or 1 week). The dependent variable was the proportion of idea units recalled for an encyclopedia. How should this be labeled? a. 4x2 between-groups ANOVA b. 2x2 within-groups ANOVA c. 2x3 within-groups ANOVA d. 2x3 between-groups ANOVATwo surfers and statistics students collected data on the number of days on which surfers surfed in the last month for 30 longboard (L) users and 30 shortboard (S) users. Treat these data as though they were from two independent random samples. Test the hypothesis that the mean days surfed for all longboarders is larger than the mean days surfed for all shortboarders (because longboards can go out in many different surfing conditions). Use a level of significance of 0.05. Longboard: 4,10,9,4,9,8,8,6,7,9,11,11,9,15,11,16,13,11,12,18,18,13,12,15,20,22,7,24,22,24 Shortboard: 6,4,4,6,9,9,6,8,4,8,8,5,9,9,4,16,12,9,13,13,10,13,11,12,14,14,9,21,19,10 Determine the hypotheses for this test.

- A 2017 random study of 10,478 Bangladesh children tracked the washing habits of the children's mothers via random survey to understand the relationship of these habits with childhood wasting. The data provided include responses from mothers to two items in this survey. The first variable represents a household's access to food: food secure, mildly food insecure, moderately food insecure, or severely food insecure. The second variable represents the mothers' responses when asked whether they use soap when washing clothes. These researchers wish to study if there is a relationship between washing habits and food security. Are the conditions for a chi-square test of independence met? Did not use Used soap soap Food secure 921 Mildly food insecure 5591 81 200 Moderately 89 food insecure 203 Severely 825 Food insecure 2568 Not enough information No YesIn an experiment, the purpose for manipulating the independent variable is to help? A. Establish the direction of the relationship by showing that the dependent variable changes when you manipulate the independent variable B. Ensure that any effects of selection or other randomization failures are minimized C. Establish the direction of the relationship and help eliminate the third variable problem D. Eliminate the third variable problem because you decide when to manipulate rather than waiting for the variable to change
