Answer: This is a deductive argument, because the truth in the first premises which states: if you get at least 8 hours of sleep a night, you show up to the office 10 minutes early for work. Has validate the conclusion that state: I know for a fact that I was early to work Monday through Friday, so I must have slept at least 8 hours every night.
The underlying reason why the conclusion is valid is because, the conclusion affirms the first premises (P1).
The conclusion can only be valid in this argument if it affirms either P1 or P2.
ANOTHER ARGUMENT WITH THE SAME PATERN IS:
P1: If it rains the soil will be wet.
P2: If it does not rain the soil will not the wet.
Conclusion: it rained, therefore the soil is wet.
