Statistics
The National Center of Education Statistics conducted a survey of high school seniors, collecting test data on reading, writing, and several other subjects. Here we examine a simple random sample of 200 students from this survey. Side-by-side box plots of reading and writing scores as well as a histogram of the differences in scores are shown below. 80- 40 30- 60- 20- 40- 10- 0- 20- read write -20 -10 10 20 Differences in scores (read - write) a) Are the reading and writing scores of each student independent of each other or can they be paired? b) Create hypotheses appropriate for the following research question: is there an evident difference in the average scores of students in the reading and writing exam? Họ: Select an answer ♥ HA: Select an answer v|? v c) The average observed difference in scores (d = read - write) is ¤d = -0.545, and the standard deviation of the differences is sa = 8.887 points. Do these data provide convincing evidence of a difference between the average scores on the two exams? scores
