Question

To find how much money the average American family spends to cool their home, 100 Alaskan families are surveyed at random. Of the families, 85 said they spend less than $75.00 per month on cooling their homes. Based off that survey, the researcher concluded that the average AMERICAN family spends less than $75.00 per month on cooling their homes.
Is this conclusion valid or not valid?

Answer 1

Answer:

Step-by-step explanation:

Statistically this is valid

But, in Alaska average daytime summer temperatures range from approximately 55 to 78 °F (12.8 to 25.6 °C); average daytime winter temperatures are about 5 to 30 °F (−15.0 to −1.1 °C). SO, they don't need cooling when compared to rest of the USA. Therefore this will not be valid.
