The town of Brant has started an after-school program for high school youth to prepare them for the ACT college entrance examination. The after-school program had 29 youth participants; the program manager compared their ACT scores with the ACT scores of 36 similar high school youth who did not participate in the after-school program. The program manager wants to determine if the after-school program had a positive effect on ACT scores. You will use the Unit 5 Dataset, given in the resources, to complete this assignment.

1. Review thetutorial in the unit study, which demonstrates t tests using two different scenarios. Then determine which type of ttest to conduct. Once you have determined that, answer the following:
   • What is the sample size?
   • What is the sample mean of each group?
2. Identify the following factors based on the table you develop in SPSS:
   • Mean difference.
   • T obtained (t).
   • Degrees of freedom (df).
   • Significance (two-tailed).
3. Write a brief narrative explaining the implications of your findings based on the value of the test statistic:
   • Would you retain or reject the null hypothesis?
   • What are limitations that must be considered in interpreting the results?
