Use this information to answer Questions 2 trough 6: A high-school teacher in alow-income urban school in Worcester, Massachusetts, used cash incentives toencourage student learning in his AP statistics class. In 2010, 15 of the 61 studentsenrolled in his class scored a 5 on the AP statistics exam. Worldwide, the proportionof students who scored a 5 in 2010 was 0.15. Is this evidence that the proportion ofstudents who would score a 5 on the AP statistics exam when taught by the teacherin Worcester using cash incentives is higher than the worldwide proportion of 0.15?Setup the appropriate null and alternative hypotesis. Continuation of Question 2. Find the p-value.tcdf(ts,999,60) = 0.017O tcdf(-999,ts,60) = 0.983O normalcdf(ts,999,0,1) = 0.015O 2*normalcdf(ts,99,0,1) = 0.03

Scenario: A guidance counselor wanted to know if anxiety differs based on time (first day of class in relation to the last day of class), and if this differs based on year in school (as a freshman, sophomore, junior, or senior). She collected data on a single group of students across their entire high school career at these eight time points — first and last day of freshman, sophomore, junior, and senior year. Anxiety was measured using a standardized scale ranging from 0 — 50, with higher scores indicating greater anxiety. Question: If p = .014 for the interaction of Time x Academic Year, what should the researcher conclude? Group of answer choices The interaction is not significant; no additional analyses are needed to interpret it. The interaction is significant; no additional analyses are needed to interpret it.
