The file P02_35.xlsx contains data from a survey of 500 randomly selected households. Researchers would like to use the available sample information to see whether home ownership rates vary by household location. For example, is there a nonzero difference between the proportions of individuals who own their homes (as opposed to those who rent their homes) in households located in the first (i.e., SW) and second (i.e., NW) sectors of this community? Use the given sample to find a 95% confidence interval that estimates this difference between proportions in home ownership rates for each pair of locations. Interpret and summarize your results.
