A researcher claims that 90% of all the residents on a certain barangay easily believes on rumors. A group of students want to verify the claim and 499 out of 569 randomly selected residents believes easily on rumors. At 0.5 level of significance, is there enough evidence to say that the claim is less than 90%? a. is the sample randomly selected? b. State the two possible outcomes. Success: Failure: c. Are the samples large enough? (Compute for np>5 and nq>5) d. Formulate the null and alternative hypothesis. Null: Alternative: e. For this problem it is left unanswered since the hypothesis has not been tested, would you it be enough to say that the claim is true or false? f. How do you compare a hypothesis that has not been tested with believing to rumors easily without any proof?
