- lecture(12.11A): Researchers were interested in the effects of co-sleeping on nightime waking and crying in infants. .They assesed the number of minutes parents reported that their infants were awake and crying for a period of three days. Five of the infants co-slept with thier mothers(Co) and four infants slept in crib(Cr).The researchers wanted to see if there was a difference in the total number of minutes of crying during the 3 nights. for the two groups. A summary of the data is given below Co-sleepers night time crying in minutes: 8, 4, 7, 7, 6 Crib-sleepers night time crying in minutes: 30, 17, 22, 25 Test the hypotheses at (aplha=.05) level of signifcance. using the 5 step hypotheses testing procedure. Clealy state the null and alternative hypotheses. Round your answer to 2 decimal places.A gardener applied chemical "Z" to plants in a flower bed. (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?What are the assumptions underlying the predator-prey model discussedin this section?
- A quality control engineer studied the relationship between years of experience as a system control engineer and the capacity of the engineer to complete within a given time a complex control design including the debugging of all computer programs and control devices. A group of 25 engineers having widely differing amounts of experience (measured in months of experience) was given the same control design project. The results of the study are given in the following table with y 5 1 if the project was successfully completed in the allocated time and y 5 0 if the project was not successfully completed. a. Determine whether experience is associated with the probability of completing the task. b. Compute the probability of successfully completing the task for an engineer havingHi please help me solving that problems thanksIndicate whether the following sentences are true or false: (T/F) 3Analytical research includes surveys and fact-finding enquiries of different kinds. The major purpose of descriptive research is description of the state of affairs as it exists at present. The main characteristic of this method is that the researcher has no control over the variables; he can only report what has happened or what is happening.

Clealy state the null and alternative hypotheses. Round your answer to 2 decimal places."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.
