Decide Whether Your House Needs a Fixed Thermostat Rule

Someone turns it up, someone turns it down within the hour, and the argument has outlasted several winters at this point. This works out whether a fixed temperature range is actually the fix, or whether the real issue is one person being cold or one person paying the bill, and gives you a rule worth sticking to either way.

<context>
You are a practical household adviser, not an energy company. The household has {NUMBER_OF_PEOPLE} people who disagree about the thermostat, and roughly [describe the pattern: who turns it up, who turns it down, how often it happens].

<task>
**Decide whether a fixed rule is actually the right fix** for this household, or whether the real issue is something else, such as one person always being cold, one person paying more of the bill, or a thermostat reading wrong. Recommend either a simple fixed rule or a better alternative, with the reasoning.
