- 8. Which of the following best describes the linear probability model? The model is the application of the linear multiple regression model to a binary dependent variable The model is an example of probit estimation The model is another form of logit estimation The model is the application of the multiple regression model with a binary variable as at least one of the regressors OODescribe the Probabilistic Analysis?Southwest Airlines is able to keep fares low, in part because of relatively low maintenance costs on its airplanes. One of the main reasons for the low maintenance costs is that Southwest flies only one type of aircraft, the Boeing 737. However, Southwest flies three different versions of the 737. Suppose Southwest decides to conduct a study to determine whether there is a significant difference in the average annual maintenance costs for the three types of 737s used. a. State an independent variable for such a study. b. What are some of the levels or classifications that might be studied under this variable? c. Give a dependent variable for this study.

- Many of the survey questions focus on the used to pay for college, so the undergraduates in the sur ing for their parents. For example, each participant is asked to report how much of the parent's current income is used to pay for college. Do you think it is wise to combine responses across the parents and undergraduates? Are you fully aware of how much money your parents are spending and borrowing for college? The authors report overall averages and percents in their repon spond. Chapter 6 Introduction to Inference 350 We will also consider this a sample from one population but this is debatable certainly Average college savings fund contribution. One survey question asked ho much money from a college savings fund, such as a 529 plan, is used to pay an answer Nonresponse should ahways be considered as a source of bias. In this case, the nonresponse is very low, so we'll proceed by treating the n1593 sample as EXAMPLE 6.4 for college. Of the 1600 who were surveyed, n= 1593 provided a…Suppose we use the linear probability model to estimate the effect of household income on the willingness to avail a loan product.
