Final answer:
The difference in temperature is 42.6°F.
Step-by-step explanation:
The difference in temperature can be found by subtracting the night temperature from the day temperature:
Difference in temperature = Day temperature - Night temperature
Difference in temperature = 36.8°F - (-5.8°F)
Difference in temperature = 36.8°F + 5.8°F = 42.6°F
Therefore, the difference in temperature is 42.6°F.
