Many stores sell extended warranties for products they sell These
Many stores sell extended warranties for products they sell. These are very lucrative for store owners. To learn more about who buys these warranties a random sample of a store’s customers who recently purchased a product for which an extended warranty was available was drawn. Among other variables each respondent reported whether they paid the regular price or a sale price and whether they purchased an extended warranty.


Can we conclude at the 10% significance level that those who paid the regular price are more likely to buy an extendedwarranty?
