What is a real life example of conjecture?

To learn about the migration behavior of California gray whales, biologists watched whales along 2 routes. For 7 days they counted the numbers of whales seen along each route. Make a conjecture on the data below:

Number of Whales Each Day

Direct Route 1 3 0 2 1 1 0

Shore Route 7 9 5 8 8 6 7

Conjecture: More whales were seen along the shore route each day.

The data supports the conjecture that most California gray whales migrate along the shoreline.
