Option B can be answered using hypothesis testing by testing the null hypothesis that the percentage of households patronizing the department store is equal to 10% versus the alternative hypothesis that it is greater than 10%. 
Option C can be answered using hypothesis testing by comparing the means or proportions of certain characteristics between the two hotels and testing the null hypothesis that there is no difference versus the alternative hypothesis that there is a difference. 
Option A could also potentially be answered using hypothesis testing by testing the relationship between familiarity with a new product, age, and education levels while controlling for income, but it would depend on the specific research question and available data.
