Hello, Please help me answer the following questions based on the Table.

? Fifty percent of users will be able to complete at least 5 tasks ? No user should make more than 4 errors for all the tasks ? More than 70% of users should agree that they are satisfied with the new ATM.

Based on these goals (i.e., have they been met?), how would you rate the usability of the new ATM?

Satis- Tasks faction Completed # of Rating Satis- Participant # (of 10) Errors (0-6) Tasks Accuracy faction Average 8 2 4.7 80% 60% 78% 73% 2 6 4 4.1 60% 20% 68% 49% 3 7 0 3.4 70% 100% 57% 76% 4 5 5 2.4 50% 0% 40% 30% 5 CO 2 5.2 90% 60% 87% 79% 6 5 4 2.7 50% 20% 45% 38% 7 10 1 5.1 100% 80% 85% 88% 8 8 1 4.9 80% 80% 82% 81% 9 7 3 3.1 70% 40% 52% 54% 10 CO 2 4.2 90% 60% 70% 73% 11 7 1 4.5 70% 80% 75% 75% 12 8 3 5.0 80% 40% 83% 68%
