ACTIVITY A. Follow the 5-step procedure to test the hypothesis of the problem using p - value approach. 1. Increasing numbers of businesses are offering child-care benefits for their workers. However, one union claims that more than 80% of firms still do not offer any child-care benefits. A random sample of 500 companies is selected, and 420 of them don't offer child - care benefits. Test the union claim at a = 0.05. 2. A learner in senior high wants to verify the estimated claim that 60% of senior high school learners in her school are registered voters. He surveyed 200 learners and found out that 116 are registered voters. Use a = 0.01 to test the hypothesis. 3. A teacher believes that 85% of students in the class will want to have modular distance learning than online distance learning. She performs a hypothesis test to determine if the percentage is the same or different from 85%. The teacher samples 50 students and 39 reply that they would want to have modular distance learning. For the hypothesis test, use a 1% level of significance
