Your friend Josh tells you that he spends less on gas in the winter than in the summer. He also says that he has to fill up his tank less often in the winter.
(a) Which of the following are possible hypotheses that can be formed from Josh’s observations? (You can choose multiple answers)
-Assuming the gas prices are the same, gas expands when the temperature is higher.
-Assuming the gas prices are the same, cars get better gas mileage when the temperature is lower.
-Assuming the gas prices are the same, Josh doesn’t drive as far in the winter as he does in the summer.
-Assuming the gas prices are the same, Josh is a lousy driver in the summer.
-Assuming the gas expansion is negligible, gas prices are higher in the winter.
The possible hypotheses that can be formed from Josh's observations are:
- Assuming the gas prices are the same, gas expands when the temperature is higher.
- Assuming the gas prices are the same, cars get better gas mileage when the temperature is lower.
- Assuming the gas prices are the same, Josh doesn't drive as far in the winter as he does in the summer.
The possible hypotheses that can be formed from Josh's observations are:
1. Assuming the gas prices are the same, cars get better gas mileage when the temperature is lower.
This hypothesis suggests that colder temperatures improve the fuel efficiency of cars, resulting in better gas mileage and fewer fill-ups.
2. Assuming the gas prices are the same, Josh doesn't drive as far in the winter as he does in the summer.
This hypothesis implies that in the winter, Josh's driving habits change, and he drives fewer miles compared to the summer. As a result, he spends less on gas and fills up his tank less often.
It is important to note that the other hypotheses mentioned in the question do not directly explain Josh's observations or are not logically connected to his observations.
