Use the following prompt to answer questions 6–10.
You are interested in examining the effectiveness of a memory training program. You conduct a study where 18 participants complete a memory test before and after the training. You plan to analyze the data using a dependent samples t test to determine whether the training program improved memory performance. Here are their memory scores (alpha = 0.05). Dataset: Before: 75, 79, 80, 72, 78, 81, 76, 77, 74, 79, 82, 73, 80, 76, 75, 78, 77, 79. After: 78, 82, 85, 76, 80, 83, 79, 80, 77, 81, 84, 75, 82, 78, 79, 82, 80, 82
i need to also find the mean difference and calculated t
