Statement 1
“The ship that requires the most maintenance per day is also the one that carried the most tonnage in the average voyage.”
Highest MHM/D = MT October at 22:17
Highest ATC (Average Tonnage of Cargo) = MT October at 167,000
They match - Consistent
Statement 2
“The ship that sailed the fewest voyages also carried the most valuable cargo, on average.”
Fewest voyages = Atlantic Carrier 119 with 8 voyages
Its CV = 30 million USD
Highest CV in the table = 45 million USD (The Kite)
They do not match - Inconsistent
Statement 3
“All of the ships that sailed the median number of voyages required less than the median number of man hours for maintenance, each day.”
Step 1: Find the median number of voyages
There are 19 ships - median is the 10th value when sorted.
Median voyages = 15.
Ships with 15 voyages:
LPG West Wind — 15:00
CC Allenway — 15:10
Pacific Carrier A — 15:52
The Good Year — 16:31
Step 2: Find the median maintenance time (MHM/D)
Sorted MHM/D - the 10th value = 16:10
Check each 15-voyage ship:
15:00 < 16:10 - OK
15:10 < 16:10 - OK
15:52 < 16:10 - OK
16:31 > 16:10 - NOT OK
One ship violates the condition - Inconsistent

Step 1: Find the median number of voyages
There are 19 ships - median is the 10th value when sorted.
Median voyages = 15.

Sorted MHM/D - the 10th value = 16:10
Check each 15-voyage ship:
15:00 < 16:10 - OK
15:10 < 16:10 - OK
15:52 < 16:10 - OK
16:31 > 16:10 - NOT OK
One ship violates the condition - Inconsistent

For statement 2, it says "most valuable cargo, on average." Wouldn't this be CV USD.M/# of voyages. In that case the information is consistent?
