1. In SUKI market, 65% of the vendors preferred to use plastic over paper bags. After the local ordinance was signed, 92 out of 120 randomly selected vendors preferred plastic over paper bags. Does this indicate that vendors in that public market have less preference in using paper bags? Use 0.05 level of significance. H₁ : p=0.65 Ha: p<0.65 2. The school principal in a certain private junior high school claimed that 35% of all students are in favor of the new PE uniform. A research teacher asked his students to verify the claim. With this, 271 out of 400 randomly selected students agreed to the new PE uniform. Using a = 0.10 level, is there enough evidence to conclude that the percentage of students who are in favor of the new PE uniform is different from 35%? Ho: p = 0.35 Ha: p > 0.35 3. A research found out that 5% of the senior high school students in a certain school are working students. A researcher randomly selected 35 out of 300 students who are working. Is there a percentage increase in the number of senior high school students who are working? Use a = 0.01 level. Ho: p = 0.05 Ha: p = 0.05
