1. For question 18, the correct decisions that generalize a correct action are i and ii because accepting the null hypothesis when it is true and rejecting it when it is false are correct actions. 2. For question 19, the saying means that what someone does is more important than what they say. 3. For question 20, the phrase with the same meaning is "Deeds are more significant than promises." 4. For question 21, the true statement is to ensure their actions align with their words to build trust. 5. For question 22, the correct null hypothesis is (H₀): μ_imports ≤ 4.7 because the test is to see if the decline led to a significant increase. 6. For question 23, the appropriate null hypothesis is (H₀): P = 90% since the plan aims to increase the literacy rate to 90%. 7. For question 24, the statement that is NOT true is that H₀ and Hₐ can be the same. Final answers: 18: A 19: C 20: A 21: B 22: B 23: A 24: C
