Reading interventions - Jasmine is a reading curriculum specialist for a large urban school district. She regularly conducts pilot studies of promising educational programs to determine if they should be implemented throughout the district. During fall term last year, she randomly selected a group of 24 eighth graders at a large middle school to participate in a supplemental tutoring program. Call this group the "Fall Cohort." At the end of the term the Fall Cohort students were evaluated using a standardized test. The sample mean score for the 24 students was 67.88 points with a standard deviation of 14.86 points. Historically, scores for students in the district on this assessment have been normally distributed with a mean of 62.7 points. Jasmine wants to use statistical inference to determine if mean scores on this exam for students in the Fall Cohort are higher than the historical mean. Round all calculated values to 4 decimal places. 1. Which set of hypotheses statements below should Jasmine use to answer her research question? OA. Ho: x = 62.7 vs. HA: > 67.88 ОВ. Но: и - 62.7 vs. Ha: и > 62.7 ос. Но: и 3D 62.7 vs. Ha: X > 67.88 OD. Ho: H = 62.7 vs. HA: µ # 62.7 2. Which of the following conditions must be met to perform this hypothesis test? Select all the correct answers. OA. The scores for students in the Fall Cohort must be normally distributed. B. The scores for all students in the district must be normally distributed. OC. We must be able to expect that at least 5 students will have scores above the historical mean. OD. The sample must be large enough so that at least 10 students fail and 10 succeed. E. The observations must be independent.
