Students at a local elementary school were randomly selected to participate in a reading fluency program. The program is designed to increase their reading fluency. A total of 17 students each took a pretest before the program and posttest after the program. The mean differences in the posttest and pretest is 11. The administration decided that all students in the school would participate in the program next school year. Let µD denote the mean difference in the student scores. The 90 percent confidence interval estimate of the mean difference for all students is (7, 15). What is an appropriate interpretation of the confidence interval? O For any HD ≥ 10, the sample result is quite likely. O up is positive, with a probability of 0.90. O up is negative, with a probability of 0.90. O up is between 7 and 15. O For any up with 7 < p <15, the sample result is quite likely.
