Hypothetical - being or involving a hypothesis : conjectural <hypothetical arguments> <a hypothetical situation>
Conjectural - of the nature of or involving or based on conjecture.
Conjecture - a: inference from defective or presumptive evidence b: a conclusion deduced by surmise or guesswork c: a proposition (as in mathematics) before it has been proved or disproved
"inference from defective or presumptive evidence" - Nothing presumptive about the evidence here.
"a conlusion deduced by surmise or guesswork" - Nothing to surmise or guess about. The numbers and procedure are clear.
"proposition (as in mathematics) before it has been proved or disproved" - The situation has been proved many times before.
A hypothetical situation would be as follows:
Paul states to his 18 year old nephew, "Marilyn Monroe would have loved me."
The inference based on defective or presumptive evidence:
a. she was married to Joe Dimaggio
b. she likes Italians
c. I am Italian
d. she would have liked me.
And for the record, my nephews are 5 and 9 and they have no idea that I like to wear women's underwear. Way too young for that. They will find out in due time.
