Question

Part 1. Answer the questions below using the scenarios provided 1. You want to investigate whether there is a difference in hours of sleep between students who work out for many hours and those who work out for a few hours. Yo u get a sample of students and interview them. During the interview, you ask each participant about the number of hours they work out and the number of hours they spend sleeping each week. Each respondent tells you how many hours they sleep, which you enter as a number (eg, 55 hours). They also tell you how many hours they spend working each week, which you also enter as a number (eg. 3). Using the data from the variable for hours spent working each week, you create a new variable, where 0- 3 or less hours and 1- more than 3 hours. Then you analyze your data. Based on your analysis, answer the following questions. (10 points) a. What is the research design of this study? b. What is the independent variable? c. What type of variable is the independent variable? d. What is the dependent variable? e. What type of variable is the dependent variable? f. What is your hypothesis (prediction)? (2) What test would you use to test your hypothesis? g. h. Explain why you would use the test above as opposed to the tijo tests we learned about in the 2. Investigators wish to study the link between exposure to a certain chemical, Exdon, and a debilitating cough among people who worked for factory X in the past. The researchers recruit a group of ex-factory workers who have the cough and a group of ex-workers who do not have the cough. The researchers develop a survey, which they administer to both groups of ex-factory workers. Ex-factory workers who have the cough are coded as 1 and those were ever in close contact with Exdon. Responses to the question about contact with Exdon are coded as O for No and 1 for Yes. Answer the following questions using this scenario. (10 points) a. What is the research design of this study? c. What type of variable is the independent variable?

Answer 1

1.The Research design of this study is to know how much the students will study n sleep.

2.
