- A group of psychologists wants to see if a 10-week self defense training program will increase the self-esteem of an adolescent student being bullied by classmates. Describe the two populations of interest and write both directional and non-directional research hypothesis with the corresponding null hypothesis for this study.It was hypothesized that there will be a difference in the average test score in Chemistry class between high schoolers who watched Breaking Bad (Group 1) and high schoolers who did not watch Breaking Bad (Group 2). Is this a non-directional or directional hypothesis? non-directional directionalIs it one tailed, or two tailed? I thought two because the hypothesis is non-directional
- Make the following directional research hypothesis into a null hypothesis: There are less females than males working as Professors at FVSU. Make the following non-directional research hypothesis into a directional hypothesis: There is a difference between the number of males and females working as Professors at FVSU.A study was conducted to determine whether first-year university students gain weight during their freshman year. The students were weighed at the beginning of the school year and three months later again. Is this a non-directional or directional hypothesis and whyBrown wants to conduct an assessment of where employees live and how employees work. Brown wanted to know if where you lived was related to how you worked. What hypothesis tests can be used in this case?
- A sociologist recorded the number of contacts entered in a cell phone and the number of texts sent in a week for 20 cell phone users. The resulting data were used to conduct a hypothesis test to investigate whether there is a linear relationship between the number of contacts and the number of texts sent. What are the correct hypotheses for the test?USA Today reported results from an Arity survey in which 2018 drivers were asked if they text while driving. Among the respondents, 42% said that they text while driving. What is the exact value that is 42% of the number of respondents? Could the result from part (a) be the actual number of respondents who said that they text while driving? Why or why not? What is the actual number of respondents who said that they text while driving? What do the results suggest about highway safety?The table below shows the jump direction which way the goalkeeper jumped and where the kick direction is from the perspective of the goalkeeper. Use .05 significance level to test the claim that the direction of the kick is independent of the direction of the goalkeeper jump
- A researcher collects data by interview on a sample of households to find out if people who read ‘quality’ daily newspapers are more knowledgeable about politics than people who read ‘tabloid’ newspapers daily. The hunch was confirmed. People who read the quality newspapers were twice as likely to respond accurately to a series of questions designed to test their political knowledge. The researcher concludes that the quality dailies induce higher levels of political knowledge than the tabloids. Assess this reasoning.In soccer, serious fouls result in a penalty kick with one kicker and one defending goalkeeper. The accompanying table summarizes results from 292kicks during games among top teams. In the table, jump direction indicates which way the goalkeeper jumped, where the kick direction is from the perspective of the goalkeeper. Use a 0.05 significance level to test the claim that the direction of the kick is independent of the direction of the goalkeeper jump. Do the results support the theory that because the kicks are so fast, goalkeepers have no time to react, so the directions of their jumps are independent of the directions of the kicks? _ Jump_Left Jump_Center Jump_RightKick_Left 58 2 35Kick_Center 44 14 29Kick_Right 46 9 55 H0: Jump direction is independent of kick direction.
