Your research group wants to explore the possibility that a particular kind of Tibetan meditation (shamata meditation) increases the capacity of iconic memory. You go to a center where experienced Tibetan Buddhist meditators regularly practice. You randomly select 10 of these people to participate in your experiment. Your dependent variable is the number of digits recalled from iconic memory. You test them before and after a 5 weeks' intensive meditation course. You predict that their iconic memory will be enhanced (better recall) as a result of the attentional training that the meditation gives. Here is the data you collect: Before: 6;6;6;7;5;7;5;5;6;6 After: 8;7;7;8;7;8;6;7;6;8 1. What is the null hypothesis? What is the alternative hypothesis? (use symbols and not words)
