- The following data was collected to explore how the average number of hours a student studies per night and the student's GPA affect their ACT score. The dependent variable is the ACT score, the first independent variable (x1�1) is the number of hours spent studying, and the second independent variable (x2�2) is the student's GPA.

Round your answer to four decimal placesOmitting a variable from our model that has a causal effect on our dependent variable always leads to omitted variable bias. a. False b. TrueA chemistry experiment is performed measuring the solubility of potassium chloride (KCl) in water at different temperatures. The goal was to determine if there is a linear relationship between the temperature of the water and how much KCl can dissolve, measured as grams per 100 milliliter (g/100mL). After the experiments were performed, the following data was collected with temperature being the independent x-variable and solubility being the dependent y-variable: Temperature (°C) x Solubility (g/100mL) y 10 31 20 33 30 37 40 41 50 42 Based on the data given for temperature and solubility of KCl and without doing any math yet, which of the following do you predict would best describe the relationship between these variables? A positive linear relationship (r close to 1) A positive linear relationship (r close to -1) A negative linear relationship (r close to 1) A negative linear relationship (r close to -1)…
- You are looking at age of first marriage’s (independent variable) effect on the age of having a first child (dependent variable): You find that B0 = 2 and B1 = 1.2 Is the B0 useful in this case? Why or why not? For these variables, what does B1 mean in words?when a regression is used as a method of predicting dependent variables from one or more independent variables. How are the independent variables different from each other yet related to the dependent variable?the following regression table where the dependent variable is the demandfor massage services in one city in the United States. Specifically, the dependent variable is the number of customers per hour (Models 1 and 2) or per day (Models 3 and 4). a) Explain why the coefficient for Population/1,000 in Model 2 is very different from the one in Model 4?

- Read the following excerpt of an article published on psychologytoday.com: “Researchers found that about 40% of college students in their study binge drink (i.e., consuming 5 or more drinks in a short amount of time) and that the vast majority of campus sexual assaults are fueled by alcohol.” Identify the variables of interest and indicate which the independent is and which the dependent variable is. Identify the classification of the independent variable (discrete or continuous) and explain the reason for your choice. Discuss what measure of central tendency is the most appropriate for each variable (independent and dependent variable) making sure to explain why.Identify the variables - Students who spend more time playing video games and working each week will have a lower GPA. 3.
