Twо (2) reаl estаte аgencies in different regiоns cоmpare the mortgage rates their clients have been receiving. The agents all feel that the mortgage rates in the eastern region have been higher than the mortgage rates in the western region. Here is a summary of their findings: Eastern Region Western Region Mean 2.01 1.97 Standard Deviation 0.023 0.032 Sample Size 26 32 A 95% confidence interval for the difference between the mean mortgage rates is (0.026, 0.054). Which of the following correctly interprets the confidence interval?

Yоu cоnduct а prоject using field dаtа from consumers in your community. Your dataset includes 5000 consumers from the large metro area in which you currently live. You run your analysis using regression and, being quite happy with the results, submit your work to the fictional (but very highly rated) Journal of the Academy of Community Marketing and Management. Eventually receive news that your work has been granted a “revise and resubmit.” Like many “revise and resubmits,” this one is deemed “high risk.” Reviewer 2 notes the following concern (which is validated by the AE and EIC, suggesting that it will be critical to correctly address if the work is to move forward): “In your city, and especially with so many individuals in your sample, there must be some sort of neighborhood effects. I know the city you are in and I know that there are at least 30 unique neighborhoods, boroughs, or districts that compose the metro area. Individuals are likely to vary by age, income, culture, background, etc. across these neighborhoods. Since your single level regression models do not account for this nesting of consumers in neighborhoods, your estimates may be biased and your findings meaningless.” The reviewer is clearly thinking about multilevel models (MLMs) in this comment. How will you respond (both in direct response to this reviewer via the reviewer response document and with regard to the changes you will actually implement, if any, into the manuscript)? Will you switch to an MLM? Why or why not? How can you tell whether MLM is appropriate for your data (I mean, it seems nested, but is there some sort of test you can use)? What if, for some reason, there is no way to capture the neighborhood-level variables you might want to control for? I know this is an imaginary constraint, but just imagine that there is no way to gather this additional data. So, you can identify which neighborhood each subject comes from, but cannot collect (or therefore model) the specific effects of variables like population, average income, etc. Is there any reason, without this data, to run an MLM? What would an MLM with no level 2 predictors do for you, if anything?
