A researcher would like to evaluate the effect of a new reading program for second-grade students. For the past five years, a standardized test given at the end of second grade has produced a mean score of µ = 45, σ = 12. A sample of n = 25 students are placed in the new program and at the end of the school year they obtain a mean test score of M = 51, s = 20. The researcher plans to use these data to test whether the new program has had a significant effect on reading scores. Which of the following hypothesis tests would be appropriate?
