No
Step-by-step explanation:
The total number of trains is 287 + 54 + 17 + 5 = 363.
Of these, the number of trains that arrived no more than 10 minutes late is 287 + 54 = 341.
The proportion is p = 341/363 = 0.94.
94% of the trains arrived no more than 10 minutes late, so the company did not meet its target.
