The Egyptian Health Department, in its Health and Hygiene Awareness Survey, surveyed residents in about 400 blocks. The survey asked residents questions about their hygiene habits. Those who regularly dust their furniture were tagged as aware, and those who did not were tagged as unaware. The following table shows results from the 2018 survey, cross-tabulating subjects’ ownership status by whether they are aware or not.

a. Identify the response variable and the explanatory variable.

b. Repeat the cell counts of subjects who were (i) aware owners and (ii) aware tenants.

c. Can you compare the counts in part b to answer the question “Is there a difference between owners and tenants who are aware?” Explain.

d. Construct a contingency table that shows the conditional proportions of sampled residents who are aware or otherwise, given ownership status. Interpret.

e. Based on part d, does it seem that there is an association between ownership status and hygiene awareness?
Explain by comparing the conditional proportions.
