Please answer using the 5 steps, thank you. A certain manager wishes to find out if the proposed system of operations increases the gross sales of the products of the compared with existing system. To compare the results, six branches for each system are randomly selected for assessment. The result is as follows: Proposed system Existing system Average sales in million X1 = 42.5 X2 = 32.6 Standard deviation s1 = 5.7 s2 = 4.8 Number of branches n1 = 6 n2 = 6 Is the proposed system significantly better than the existing system? Test at a = 0.01 and use a one-tailed test.

Question
Please answer using the 5 steps, thank you.
A certain manager wishes to find out if the proposed system of operations increases the gross sales of the products of the compared with existing system. To compare the results, six branches for each system are randomly selected for assessment. The result is as follows:
| Proposed system | Existing system | |
| Average sales in million | X1 = 42.5 | X2 = 32.6 |
| Standard deviation | s1 = 5.7 | s2 = 4.8 |
| Number of branches | n1 = 6 | n2 = 6 |
Is the proposed system significantly better than the existing system? Test at a = 0.01 and use a one-tailed test.
