Suppose that as part of a research methods class, Bailey was asked to write summaries of research papers on the following topics. • The effects of employing interactive teaching methods on students' problem-solving skills • The effects of media coverage on community support for crime prevention For each topic, identify the explanatory and the response variables. a) Whether an interactive teaching method was used and the amount of media coverage are the response variables, and the development of students' problem-solving skills and the level of community support for crime prevention are the explanatory variables. b) Whether an interactive teaching method was used and the level of community support for crime prevention are the explanatory variables, and the amount of media coverage and the development of students' problem-solving skills are the response variables. c) Whether an interactive teaching method was used and the amount of media coverage are the explanatory variables, and the development of students' problem-solving skills and the level of community support for crime prevention are the response variables. d) Whether an interactive teaching method was used and the development of students' problem-solving skills are the response variables, and the amount of media coverage and the level of community support for crime prevention are the explanatory variables. Select the statements that are true of the least-squares regression model. is based on sample data assumes that the mean response has a straight-line relationship with the explanatory variable x features known parameters representing the slope and intercept predicts the mean response for each value of the explanatory variable x is defined in terms of two population parameters representing the slope and intercept
