An educator believes that new directed reading activities in the classroom will help elementary school pupils improve some aspects of their reading ability. She arranges for two third grade classes of students to take part in these activities. A third class of students in the same school is treated as control and does not take part in the reading activities. At the end of 8 weeks, all students are given a Degree of Reading Power (DRP) test, which measures the aspects of reading ability that the treatment is designed to improve. The educator wishes to see if the directed reading program increases scores on the DRP test. I conducted a confidence interval on this data and found the interval to be 1.5 to 16.5. Does this indicate a true difference between the new reading activities and the control? There is not enough information No Yes
