1. In a public senior high school, a survey conducted last year showed that 30% of the students' parents are farmers. This year, a new survey was conducted randomly on 150 students from the same school. It was found that 53 of them have parents who are farmers. Test if the claim was higher at a = 0.01 level. Ho: p = 0.30 Ha: p > 0.30 a. b. Level of Significance: a = 0.01 c. Computed Test Statistic: Zcom = d. Critical Value: 2.33 e. DECISION: Since the computed test statistic Zoom = the rejection region, does not fall in the null hypothesis (Ho). CONCLUSION: Therefore, we conclude that at 0.01 level of significance, evidence to claim that "
