Estimating home energy use per day really depends on how much heating/air conditioning you need, if your heater is gas powered or not. The fridge is like 1kWh per day. So... 100 days of just the fridge.
Mid-sized gas furnace will pull about 600W to run the forced air fan. So... 0.6 kWh per hour of runtime. You'd have to calculate the runtime given a temperature. If it is an electric furnace it'll blow through that battery quite fast.
Lights are now peanuts, because LED bulbs are about 8-10W. .12kWh per bulb per day for 12 hours of use.
Average of 877kWh per month. Of course this is averaged as you use more power depending on local weather and time of year due to heating/cooling needs. With that over-averaged value, 3.75 days to drain the battery. This is probably why Ford says about 3 days and then says "10 with conservation".
So I'd say if a family really conserved on heating/cooling, and attempted to be careful with cooking, that battery could quite easily go 10 days.
One, we don't know the actual usable capacity of the pack, because Ford hasn't said. Forbes writer estimates 110-130kWh.

Also, compare your home's electric bill for a kWh number to compare: https://www.eia.gov/tools/faqs/faq.php?id=97&t=3
