Use this information to answer Questions 2 trough 6: A high-school teacher in a low-income urban school in Worcester, Massachusetts, used cash incentives to encourage student learning in his AP statistics class. In 2010, 15 of the 61 students enrolled in his class scored a 5 on the AP statistics exam. Worldwide, the proportion of students who scored a 5 in 2010 was 0.15. Is this evidence that the proportion of students who would score a 5 on the AP statistics exam when taught by the teacher in Worcester using cash incentives is higher than the worldwide proportion of 0.15? Setup the appropriate null and alternative hypotesis. Have you met the large sample required for this inference? No. Even if n(1– po) is larger than 10, npo is smaller than 10. Yes. npo is smaller than 10. But we shouldn't be worried because n(1- po) is larger than 10. Yes. Both np andn(1 – p) are larger than 10. Yes. The sample size is 61, which is larger than 30.
