- lecture(11.14): A professor offered a course that was offered half online and half in person. The professor hypothesized that students were spending less time on the material than on the off line material. At the end of the semester, students were asked to provide the amount of time they tended to course tasks during a week. The weeks were classified as online or in person, and the average amount of time is provided for 15 students. Online: 4 3 5 6 2 2 4 7 5 4 3 2 6 6 3 In person: 5 5 4 7 3 4 4 6 4 5 3 4 5 8 4 Test the hypothesis at( alpha=0.05) level of significance using the 5 step procedure. Make sure to clearly state the null and alternative hypothessis. Round your answer to 2 decimal places.The Dependent variable is the Effectiveness of a new therapeutic technique or Recall on intrusive thougnts? Why?Does moderate alcohol consumption impact the performance of heavy machinery opera- tors in the workplace? A large stevedoring company studied the time on task (in seconds) to complete a complex manoeuvre by crane operators on the dock, firstly in a completely sober condition, and then five days later, after consuming a moderate amount of alcohol (as measured by a blood alcohol test). The data are given below: Operator Time taken while sober Time taken after consuming alcohol 2 3 4 5 6 9 10 186 375 310 240 220 420 410 205 250 900 262 565 800 630 285 365 405 735 425 900 (a) Does moderate alcohol consumption increase the time it takes to complete a complex crane manoevure on the docks? Use an appropriate non-parametric test at a = 0.05 to support your conclusion. (b) Give a normal approximation to the above test (ignore that n is less than 25). Comment on the outcomes of the two different tests at the 1% level of significance.
- I can relate Professor Jody Gittell analyzed workers inthe health care system. Specifically, she was interested tosee if relational coordination (communicating and relatingfor the purpose of task integration) makes a worker more resilient in response to external threats that require a coor-dinated response across multiple roles in the organization. She rated whether physicians and nurses were selected for teamwork qualities, on a scale of 0 to 2. Do these summa-ries show evidence that teamwork qualities are valued dif-ferently in doctors than in nurses? Assume the conditions for inference have been met.

(S)he observed that the plants grew dramatically during the next two weeks. Using only the information from the previous two sentences, write a hypothesis about the effect of chemical "Z" on plants. (Note: Your hypothesis must be a testable statement.) A researcher conducted a series of experiments to test the effect of chemical “Z” on plants. The data from the experiments is summarized in the graph below. (Image of the Graph attached.) Interpret the graph above. What did the researcher learn about the effect of chemical “Z?” Based on the researcher’s graph, what can you conclude about the hypothesis you wrote for Question 7 above?
- Can you guys help me on this? Thank you!use calculator methodHow is the hatching of water python eggs influenced by the temperature of the snake's nest? Researchers randomly assigned newly laid eggs to one of three water temperatures: hot, neutral, or cold. Hot duplicates the extra warmth provided by the mother python, and cold duplicates the absence of the mother. The table shows the result of the experiment. The researchers will use a chi-square test for homogeneity to analyze the findings. Hatching status Yes No Total Cold 16 11 27 Water Temperature Neutral Hot 38 75 18 56 104 Total 129 58 187 Which of the following is false? All of the conditions are met for conducting a chi- square test for homogeneity. The data came from 3 groups in a randomized experiment. All expected counts are at least 5. The 10% condition is met. The 10% condition is not needed because the eggs were not randomly selected from the population. Incorrect
- "A researcher investigated the short-term effect of including classical music on the standard relaxation therapy used in the treatment of smoking. The researcher investigated whether slow classical music when included with relaxation therapy has any significant effect on the behavior of smoking cigarettes. The slow classical music used with the therapy is the “Piano Concerto in A minor” by Edvard Grieg. A piano concerto is a type of concerto, a solo composition in the classical music genre, which is composed for a piano player and is typically accompanied by an orchestra or other large ensemble. Participants who smoked at least one pack of cigarettes a day (20 cigarettes in a pack) were randomly assigned to one of two groups. The participants in condition one received relaxation therapy that included classical music. The second condition consisted of participants who served as a control group and were given the same relaxation therapy but did not include the slow classical music.
