8. Do stain-polyurethane mixes protect wood as well as stain and polyurethane applied in separate coats? Five types of wood will be used, with two boards of each type of wood. One board of each type of wood (randomly selected) will have the stain-polyurethane mix applied to it, and the other will have stain and polyurethane applied in separate coats. Each board will have water poured on it, and the amount of water retained will be measured. Which significance test is most appropriate? (A) A chi-square test for goodness of fit (B) A one-sample z-test for a proportion (C) A matched-pair t-test for a mean difference (D) A two-sample t-test for a difference between two means (E) A two-sample z-test for a difference between two proportions
