The table shows the credit scores for 12 randomly selected adults who are considered high-risk borrowers before and two years after they attend a personal finance seminar. At a = 0.01, is there enough evidence to support the claim that the seminar helps adults increase their credit scores? Assume the populations are normally distributed.
Adult | 1 | 2 | 3 | 4 | 5 | 6 | |
Credit score (before seminar) | 608 | 620 | 610 | 650 | 640 | 680 | |
Credit score (after seminar) | 646 | 692 | 715 | 669 | 725 | 786 | |
