Which of the following statements(hypotheses) could be tested by quantitative measurement?

Question

a. Ty Cobb was a better hitter than Pete Rose.

b. Ivory soap is 99.44% pure.

c. Rolaids consume 47 times its weight in excess stomach acid.

Answer 1

I think (a) can be tested as such, by measuring the difference in the number of hits by each hitter.

(b) I think probably not. Because... how do you define pure? Pure could mean anything

(c) I think you could possibly measure this.
